Description

L'invention se rattache au secteur technique de la sécurité des voies de circulation routières ou autoroutières.The invention relates to the technical sector of track safety road or motorway traffic.

Plus particulièrement, l'invention concerne une barrière de sécurité équipée d'un écran de protection.More particularly, the invention relates to a security barrier equipped with a protective screen.

De manière parfaitement connue pour un homme du métier, une glissière de sécurité pour routes ou autoroutes comprend essentiellement au moins une lisse fixée à la partie supérieure de poteaux par l'intermédiaire d'éléments faisant office d'écarteur. Généralement là où les lisses ont un profil transversal sensiblement en forme d'oméga. La fixation de la lisse par rapport aux écarteurs, d'une part, et la fixation des écarteurs par rapport aux poteaux d'autre part, peuvent être effectuées par différents moyens.In a manner perfectly known to a person skilled in the art, a crash barrier for roads or highways basically includes at minus a stringer attached to the top of the posts via elements acting as a retractor. Generally where the beams have a transverse profile substantially in the shape of an omega. The fixing of the beam by on the one hand, and the fixation of the spacers on the other posts on the other hand, can be carried out by different means.

Pour augmenter la sécurité des motocyclistes notamment, on a proposé d'équiper ce type de glissière de sécurité d'un écran de sécurité disposé dans la partie inférieure de l'ensemble de glissière. Selon les normes en vigueur, cet écran de protection est déterminé pour offrir une surface plus importante au contact du corps du cycliste accidenté, en ayant pour objectif de permettre son glissement afin d'évacuer l'énergie du choc. Cet écran doit posséder une certaine capacité d'amortissement.To increase the safety of motorcyclists in particular, it has been proposed to equip this type of safety barrier with a safety screen arranged at the bottom of the slide assembly. According to the standards in force, this protective screen is determined to provide a more important in contact with the body of the injured cyclist, with the objective allow its sliding in order to evacuate the energy of the shock. This screen should have some amortization capacity.

Différentes solutions ont été proposées, comme il ressort par exemple de l'enseignement des demandes de brevets EP 1182296 et EP 1184515. L'une et l'autre de ces demandes de brevets proposent plusieurs solutions techniques permettant la fixation d'un écran dans un plan sensiblement vertical et en retrait du plan vertical défini par la lisse supérieure. Quelles que soient les solutions techniques proposées, il apparaít que l'écran de protection est fixé directement par l'intermédiaire d'éléments rapportés en relation aux organes d'assemblage de la lisse supérieure sur l'écarteur. Compte tenu de ce montage, il en résulte que sous l'effet d'un choc, l'amortissement est simplement obtenu par basculement de l'ensemble de l'écran par rapport à la zone de fixation au niveau de l'écarteur, en direction du poteau. Cet amortissement est donc très limité.Different solutions have been proposed, as shown for example teaching of patent applications EP 1182296 and EP 1184515. Both of these patent applications offer several solutions techniques for fixing a screen in a plane substantially vertical and set back from the vertical plane defined by the top rail. What whatever the technical solutions proposed, it appears that the screen protection is fixed directly by means of elements added in relation to the assembly members of the upper arm on the spacer. Given this arrangement, it follows that under the effect of a shock, amortization is simply obtained by tilting the assembly of the screen in relation to the fixing area at the spacer, in direction of the post. This amortization is therefore very limited.

L'invention s'est fixée pour but de remédier à ces inconvénients de manière simple, sûre, efficace et rationnelle.The object of the invention is to remedy these drawbacks of simple, safe, efficient and rational way.

Le problème que se propose de résoudre l'invention, est d'augmenter l'effet d'amortissement en cas de choc sur l'écran de protection, en recherchant un effet d'enfoncement progressif de l'écran en direction du poteau et non plus un simple effet de basculement en direction dudit poteau.The problem which the invention proposes to solve is to increase the damping effect in the event of an impact on the protective screen, in looking for a progressive penetration effect of the screen towards the post and no longer a simple tilting effect towards said post.

Pour résoudre le problème posé, il a été conçu et mis au point un dispositif de fixation d'un écran de protection pour glissières de sécurité de voie de circulation, qui comprend des organes supports présentant chacun une partie d'appui apte à être fixée sur le poteau, ladite partie étant prolongée par une zone déformable élastiquement en faisant office d'amortisseur d'énergie, ladite zone présentant des agencements pour assurer la fixation de l'écran dans un plan sensiblement vertical, en retrait du plan vertical défini par la lisse. To solve the problem, it was designed and developed a device for fixing a protective screen for crash barriers traffic lane, which comprises support members each having a support part capable of being fixed on the post, said part being extended by an elastically deformable zone by acting energy absorber, said zone having arrangements for securing the screen in a substantially vertical plane, set back of the vertical plane defined by the beam.

En vue d'améliorer l'effet d'amortissement recherché, l'extrémité libre de la zone déformable élastiquement, présente des agencements d'appui et de centrage avec le poteau.
   Pour résoudre le problème posé de permettre un enfoncement progressif de l'écran en direction des poteaux, la zone déformable élastiquement présente une partie centrale rectiligne agencée pour la fixation de l'écran, ladite partie étant prolongée symétriquement, de part et d'autre, par deux segments rectilignes disposés angulairement pour faire office d'amortisseur, lesdits segments étant raccordés aux parties d'appui avec le poteau.In order to improve the desired damping effect, the free end of the elastically deformable zone has support and centering arrangements with the post.
To solve the problem posed of allowing a progressive depression of the screen in the direction of the posts, the elastically deformable zone has a rectilinear central part arranged for fixing the screen, said part being extended symmetrically, on either side, by two rectilinear segments arranged angularly to act as a shock absorber, said segments being connected to the support parts with the post.

Pour résoudre le problème posé d'assurer la fixation de l'écran sur les poteaux de la lisse supérieure, la partie d'appui et de fixation de l'organe support présente des agencements pour être fixée en combinaison avec le (ou les) organe(s) d'assemblage de l'écarteur à la partie supérieure du poteau. Ces agencements sont constitués par une lumière oblongue en communication avec une lumière transversale débouchante pour l'engagement de l' (ou des) organe(s) d'assemblage.To solve the problem posed of securing the screen on the posts of the top rail, the support and fixing part of the support member has arrangements to be fixed in combination with the spacer assembly (s) at the top of the post. These arrangements are constituted by an oblong light in communication with a transverse through light for the engagement of the assembly member (s).

Compte tenu du problème posé à résoudre, les agencements d'appui et de centrage de l'extrémité libre de la zone déformable avec le support, sont constitués par deux pattes équerrées aptes à enserrer la section du poteau.Given the problem to be solved, the support arrangements and centering the free end of the deformable zone with the support, consist of two squared legs capable of enclosing the section of the post.

Selon une forme de réalisation préférée, et toujours pour résoudre le problème posé d'amortir les chocs, l'écran est constitué par une ou plusieurs nervures en creux et en relief formées longitudinalement sur sa totalité de la longueur, les nervures en creux présentant des ouvertures pour le passage d'organes d'assemblage avec la partie centrale de fixation de la zone déformable de l'organe support. Les nervures sont de section trapézoïdale. Il en résulte que la forme des nervures participe à l'effet d'amortissement recherché.According to a preferred embodiment, and always to resolve the problem posed to absorb shocks, the screen consists of one or more several hollow and raised ribs formed longitudinally on its the entire length, the hollow ribs having openings for the passage of assembly members with the central fixing part of the deformable area of the support member. The ribs are of section trapezoidal. As a result, the shape of the ribs contributes to the effect amortization sought.

On observe également que les organes d'assemblage de l'écran sur chacun des supports sont situés dans les nervures en creux de sorte que ces derniers ne constituent pas une partie proéminente, éliminant ainsi toute partie agressive.It is also observed that the assembly members of the screen on each of the supports are located in the hollow ribs so that these do not constitute a prominent part, thus eliminating any aggressive part.

L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels :

  • La figure 1 est une vue en perspective de l'un des supports de l'écran.
  • La figure 2 est une vue en perspective d'une forme de réalisation de l'écran.

The invention is set out below in more detail with the aid of the figures of the accompanying drawings in which:
  • Figure 1 is a perspective view of one of the supports of the screen.
  • Figure 2 is a perspective view of an embodiment of the screen.
  • Figures 3, 4 and 5 are transverse views showing the height adjustment of the screen by means of the fixing device according to the invention.

D'une manière parfaitement connue, la glissière de sécurité présente généralement au moins une lisse supérieure (L) fixée sur différents poteaux (P) par l'intermédiaire d'écarteurs (E). Les lisses (L), les écarteurs (E) et les poteaux (P) sont en métal, par exemple en acier galvanisé. Les écarteurs sont fixés à l'extrémité supérieure des poteaux (P) au moyen de boulons (B), tandis que les lisses (L) sont fixées à l'extrémité des écarteurs (E) au moyen de boulons (B1). De même, l'extrémité des lisses (L) présente des agencements pour l'accouplement en position d'alignement de plusieurs lisses fixées le long de la voie de circulation à équiper.In a perfectly known manner, the safety barrier presents generally at least one top rail (L) fixed on different posts (P) via spacers (E). The beams (L), the spacers (E) and the posts (P) are made of metal, for example galvanized steel. The retractors are fixed to the upper end of the posts (P) by means of bolts (B), while the rails (L) are fixed to the end of the spacers (E) at means of bolts (B1). Similarly, the end of the heddles (L) has arrangements for coupling in alignment position of several rails fixed along the traffic lane to be fitted.

Comme indiqué, le but recherché selon l'invention est d'équiper la glissière de sécurité d'un écran de protection (1) pour éviter notamment aux motocyclistes, en cas d'accident et en cas de chocs ou de glissades, de venir s'encastrer au niveau notamment des poteaux. Dans ce but, il est nécessaire de fixer l'écran (1) dans un plan sensiblement vertical et en retrait du plan vertical défini par la lisse (L).As indicated, the aim sought after according to the invention is to equip the safety barrier with a protective screen (1) to prevent in particular motorcyclists, in the event of an accident and in the event of impacts or slips, to come to be embedded in the level in particular of the posts. For this purpose, it is necessary to fix the screen (1) in a substantially vertical plane and in withdrawal of the vertical plane defined by the arm (L).

Selon une caractéristique à la base de l'invention, l'écran de protection (1) est fixé par rapport à la glissière (L) au moyen d'un dispositif apte à faire office d'amortisseur d'énergie en cas de chocs. Dans ce but, le dispositif de fixation selon l'invention comprend pour chaque lisse, des organes support (2) en nombre correspondant avantageusement, mais non limitativement, au nombre de poteaux ou d'écarteurs.According to a characteristic underlying the invention, the screen of protection (1) is fixed relative to the slide (L) by means of a device able to act as an energy absorber in the event of impact. For this purpose, the fixing device according to the invention comprises, for each boom, support members (2) in corresponding numbers advantageously, but not limitatively, to the number of posts or spacers.

Les organes supports (2) présentent une partie d'appui (A) apte à être fixée sur le poteau (P) comme indiqué dans la suite de la description. Cette partie (A) est prolongée par une zone (D) déformable élastiquement en faisant office d'amortisseur d'énergie. Cette zone (D) présente en outre des agencements pour assurer la fixation de l'écran (1) dans les conditions indiquées précédemment, c'est-à-dire dans un plan sensiblement vertical en retrait du plan vertical défini par la lisse supérieure (L). The support members (2) have a support part (A) capable of being fixed to the post (P) as indicated in the following description. This part (A) is extended by an elastically deformable zone (D) in acting as an energy absorber. This area (D) also presents arrangements for securing the screen (1) under the conditions indicated above, that is to say in a substantially vertical plane at removal of the vertical plane defined by the top rail (L).

Avantageusement, chacun des organes support (2) est réalisé à partir d'un fer de section méplate, de largeur constante et convenablement plié pour constituer la zone de fixation (A), la zone faisant office d'amortisseur (D) et une zone (C) de positionnement et de centrage par rapport à la partie inférieure du poteau (B).Advantageously, each of the support members (2) is produced from a flat iron, of constant width and suitably folded to constitute the fixing zone (A), the zone acting as a shock absorber (D) and a zone (C) for positioning and centering with respect to the part bottom of post (B).

La zone (D) présente une partie centrale rectiligne (2a) agencée pour la fixation de l'écran (1). Par exemple, la partie centrale rectiligne (2a) présente une lumière oblongue (2a1) pour l'engagement d'organes d'assemblage (3) du type boulons par exemple. Cette partie centrale (2a1) est prolongée symétriquement, de part et d'autre, par deux segments rectilignes (2b) et (2c) disposés angulairement pour faire office d'amortisseurs. Les segments (2c) sont raccordés à des parties d'appui (2d) et (2e) aptes à être disposés facialement contre le poteau correspondant (P).Zone (D) has a rectilinear central part (2a) arranged for the fixing the screen (1). For example, the straight central part (2a) has an oblong lumen (2a1) for organ engagement assembly (3) of the bolt type for example. This central part (2a1) is extended symmetrically on both sides by two segments rectilinear (2b) and (2c) arranged angularly to act shock absorbers. The segments (2c) are connected to support parts (2d) and (2e) able to be arranged face to face against the corresponding post (P).

La partie d'appui supérieure (2d) présente une lumière oblongue (2d1) en communication avec une lumière transversale débouchante (2d2) pour l'engagement du ou des organes d'assemblage (B) de l'écarteur (E) sur le poteau (P).
   La partie d'appui inférieure (2e) présente deux pattes latérales équerrées (2e1) aptes à enserrer la section du poteau, assurant ainsi le centrage de l'ensemble de l'organe support (1). Compte tenu de la lumière (2d1), il est possible de régler facilement en hauteur l'organe support (1) par rapport aux poteaux, pour modifier, d'une manière concomitante, le positionnement de l'écran (1). The upper support part (2d) has an oblong opening (2d1) in communication with a through transverse opening (2d2) for the engagement of the assembly member (s) (B) of the spacer (E) on the post (P).
The lower support part (2e) has two squared lateral tabs (2e1) capable of enclosing the section of the post, thus ensuring the centering of the whole of the support member (1). Given the light (2d1), it is possible to easily adjust the height of the support member (1) relative to the posts, to modify, concomitantly, the positioning of the screen (1).

On renvoie aux figures 3, 4, et 5 montrant différents réglages possibles. La figure 3 montre un positionnement considéré comme normal de l'écran. La figure 4 montre un positionnement de l'écran pour éviter un obstacle au sol, tandis que la figure 5 montre un réglage en position basse de l'écran.We refer to Figures 3, 4, and 5 showing different possible settings. Figure 3 shows a positioning considered normal for the screen. Figure 4 shows a positioning of the screen to avoid an obstacle to the ground, while Figure 5 shows a setting in the lower position of the screen.

Compte tenu de ces dispositions, il apparaít que les supports (2) de l'écran (1) avec des appuis haut et bas et avec la forme géométrique de la zone (D), permet d'obtenir un fonction d'amortisseur très efficace. On observe également que le support (2) de l'écran (1) est fixé directement sur le poteau (P) de sorte qu'il travaille indépendamment de la lisse (L), étant donné qu'il n'y a aucune liaison entre ledit écran et ladite lisse (L).Given these provisions, it appears that the supports (2) of the screen (1) with top and bottom supports and with the geometric shape of the zone (D), provides a very effective damper function. We also observe that the support (2) of the screen (1) is fixed directly on the post (P) so that it works independently of the rail (L), being given that there is no connection between said screen and said beam (L).

Selon une autre caractéristique, en ayant toujours pour objectif d'augmenter l'effet d'amortissement, l'écran (1) est constitué par plusieurs nervures en creux (1a) et en relief (1b) formé longitudinalement sur la totalité de sa longueur. Les nervures en creux (1a) présentent des ouvertures pour le passage des organes d'assemblage (3). Les nervures (1a) et (1b) sont de section sensiblement trapézoïdale.
   Il en résulte qu'après mise en place des organes d'assemblage (3), ces derniers ne débordent pas des nervures en relief (1b). Dans ces conditions, aucune partie n'est en saillie.According to another characteristic, always having the objective of increasing the damping effect, the screen (1) is constituted by several hollow ribs (1a) and in relief (1b) formed longitudinally over its entire length. . The hollow ribs (1a) have openings for the passage of the assembly members (3). The ribs (1a) and (1b) are of substantially trapezoidal section.
It follows that after the assembly members (3) have been put in place, the latter do not protrude from the raised ribs (1b). Under these conditions, no part is protruding.

De même, la partie de recouvrement d'une des extrémités de l'écran (1), est de dimensions réduites, résultant d'une déformation sur la totalité de sa hauteur. Ces dispositions permettent le chevauchement et l'appui de l'extrémité d'un autre écran aligné dans le même plan pour réaliser un emboítement sans aucune partie saillante. Similarly, the covering part of one end of the screen (1), is of reduced dimensions, resulting from a deformation on the whole of its height. These provisions allow the overlap and support of the end of another screen aligned in the same plane to make a interlocking without any projecting part.

Les rainures en creux et en relief participent à une bonne résistance de l'ensemble de l'écran et lui assure une meilleure élasticité comme indiqué.The recessed and raised grooves contribute to good resistance of the entire screen and gives it better elasticity as indicated.
