Abstract
Description
L'invention se rattache au secteur technique des glissières de sécurité pour voies de circulation, du type route et autoroute.The invention relates to the technical sector of roadway safety barriers, road and highway type.
D'une manière parfaitement connue pour un homme du métier, une glissière de sécurité est composée, pour l'essentiel, de poteaux support battus au sol recevant, à leur extrémité supérieure, généralement par l'intermédiaire d'écarteurs, une lisse dont le profil en section transversal peut être profilé sensiblement en forme d'omega. Le plus souvent, l'ensemble de la glissière est réalisé en acier, notamment en acier galvanisé.In a manner that is well known to a person skilled in the art, a guardrail is essentially composed of support poles beaten to the ground receiving, at their upper end, generally by means of spacers, a rail whose transverse section profile can be shaped substantially omega-shaped. Most often, the entire slide is made of steel, especially galvanized steel.
Ce type de glissière peut également être équipé d'un écran de protection complémentaire positionné sous la lisse supérieure. La fonction de cet écran est d'éviter aux véhicules deux roues notamment, de passer sous la glissière supérieure, notamment en cas de chute pouvant provoquer un glissement du véhicule. Le plus souvent la fixation de ces écrans s'effectue, par l'intermédiaire de bras support, à une partie du poteau, de la lisse ou de l'écarteur. De telles dispositions ne sont pas décrites car parfaitement connues pour un homme du métier et susceptibles de présenter différentes variantes de réalisation.This type of slide can also be equipped with a complementary protective screen positioned under the upper rail. The function of this screen is to avoid two-wheel vehicles in particular, to pass under the upper slide, especially in case of a fall that can cause a sliding of the vehicle. Most often the fixing of these screens is effected, by means of support arm, to a portion of the post, the rail or the spacer. Such provisions are not described because they are well known to those skilled in the art and may have different embodiments.
Avec ce type de glissière de sécurité, il est apparu important de pouvoir protéger les usagers des chocs, non seulement au niveau d'une zone intermédiaire considérée selon une partie de la longueur de la glissière, mais au niveau notamment de la zone d'extrémité de cette dernière considérée dans le sens de circulation.With this type of guardrail, it appeared important to be able to protect users from shocks, not only at an intermediate zone considered along part of the length of the slide, but especially at the end zone. of the latter considered in the direction of circulation.
A cet égard, différentes solutions ont été proposées. On peut citer, par exemple, l'enseignement du brevet FR 2.848.230 qui prévoit d'équiper les poteaux support d'un manchon en bois pour tenter de diminuer la gravité des chocs.In this respect, different solutions have been proposed. We can cite, for example, the teaching of patent FR 2,848,230 which plans to equip the posts support a wooden sleeve to try to reduce the severity of shocks.
Une autre solution ressort de l'enseignement du brevet FR 2.788.796 qui prévoit d'équiper le poteau support de boucliers de forme arrondie.Another solution emerges from the teaching of FR 2,788,796 which provides to equip the support post shields rounded.
Il apparaît que ces différentes solutions ne peuvent éventuellement amortir le choc qu'au niveau des poteaux support. Demeure par conséquent le problème de la protection de l'extrémité de l'écran (éventuellement de la lisse) qui constitue une partie saillante. Il pourrait être envisagé de recourber cette extrémité débordante en constituant une forme arrondie. On conçoit que cette solution n'est pas rationnelle et nécessite de réaliser un écran de forme spéciale, ce qui nuit à la standardisation.It appears that these different solutions can possibly dampen the shock only at the level of the support posts. Therefore remains the problem of protecting the end of the screen (possibly the smooth) which is a salient part. It could be envisaged to curl this overflowing end by constituting a rounded shape. It is conceivable that this solution is not rational and requires the realization of a screen of special shape, which is detrimental to standardization.
On a proposé également des embouts de protection adaptables aux extrémités de la partie débordante de l'écran. Généralement, ces embouts présentent une partie destinée à être fixée à l'écran et une autre partie destinée à être fixée au niveau du poteau support d'extrémité en combinaison avec des pattes rapportées. Il en résulte un nombre de pièces important avec des difficultés de montage.It has also been proposed protective caps adaptable to the ends of the projecting portion of the screen. Generally, these tips have a portion to be attached to the screen and another portion to be fixed at the end support pole in combination with inserts tabs. This results in a large number of parts with mounting difficulties.
L'invention s'est fixée pour but de remédier à ces inconvénients d'une manière simple, sûre, efficace et rationnelle.The object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.
Le problème que se propose de résoudre l'invention est de réaliser un embout de protection adaptable notamment aux extrémités d'un écran de glissière de sécurité routière (éventuellement adaptable à l'extrémité de la lisse de la glissière), d'une manière particulièrement simple, en évitant l'utilisation d'éléments de liaison rapportés, tout en augmentant l'effet d'amortissement recherché en cas de choc.The problem to be solved by the invention is to provide a protective cap adaptable in particular to the ends of a road safety barrier screen (possibly adaptable to the end of the rail of the slider), particularly simple, avoiding the use of reported connection elements, while increasing the damping effect sought in case of shock.
Pour résoudre ce problème, il a été conçu et mis au point un embout de protection pour écran de glissière de sécurité routière, ledit écran étant accouplé à un bras support rendu solidaire d'un poteau recevant au moins une lisse. Selon l'invention, l'embout présente une partie d'appui apte à coopérer avec la section interne de l'extrémité de l'écran débordant du poteau, ladite partie étant prolongée par une forme arrondie terminée par une patte doublement équerrée pour délimiter, avec ladite forme arrondie, une structure totalement fermée faisant office d'amortisseur et disposée devant le poteau, l'une des ailes de la patte doublement équerrée coopérant avec des moyens d'assemblage engagés dans des agencements de la partie d'appui en vue d'être fixée audit écran.To solve this problem, it was designed and developed a protective cap for road safety barrier screen, said screen being coupled to a support arm secured to a pole receiving at least one rail. According to the invention, the endpiece has a bearing portion capable of cooperating with the internal section of the end of the screen projecting from the post, said part being extended by a rounded shape terminated by a doubly squared leg to delimit, with said rounded shape, a completely closed structure acting as a shock absorber and disposed in front of the post, one of the wings of the doubly squared leg cooperating with assembly means engaged in arrangements of the support part for the purpose of be attached to said screen.
Pour résoudre le problème posé d'éviter les chocs directs avec l'extrémité de l'écran, d'une part, et avec le poteau support, d'autre part, tout en ayant un effet d'amortissement, la patte doublement équerrée délimite transversalement une section en U dont la branche commune de liaison entre les deux ailes, est située, après fixation au moyen de la partie d'appui, devant le poteau et dans un plan sensiblement parallèle à ce dernier. La branche commune est sensiblement en appui contre le poteau.To solve the problem of avoiding direct shocks with the end of the screen, on the one hand, and with the support post, on the other hand, while having a damping effect, the doubly squared leg delimits transversely a U-shaped section whose common connecting branch between the two wings, is located, after attachment by means of the bearing portion, in front of the pole and in a plane substantially parallel to the latter. The common branch is substantially in support against the pole.
Pour résoudre le problème posé de faciliter la fixation de l'embout en utilisant notamment les moyens d'assemblage que présente l'écran de sécurité en vue de sa fixation, les agencements de fixation de la partie d'appui, à l'extrémité de l'écran, coopèrent avec des organes d'assemblage de l'écran avec le bras support.To solve the problem posed to facilitate the attachment of the nozzle using in particular the assembly means that the security screen has for fixing it, the fixing arrangements of the support part, at the end of the screen, cooperate with screen assembly members with the support arm.
Sans pour cela sortir du cadre de l'invention, la partie d'appui peut être profilée pour coopérer et être fixée au niveau de l'extrémité de la section interne de la lisse.Without departing from the scope of the invention, the support portion may be profiled to cooperate and be fixed at the end of the inner section of the bar.

Comme indiqué, l'invention trouve une application particulièrement avantageuse dans le cas de glissières de sécurité pour route ou autoroute.As indicated, the invention finds a particularly advantageous application in the case of guard rails for road or highway.
D'une manière parfaitement connue, ce type de glissière résulte d'un assemblage de lisses (L) en alignement sur des poteaux support (P), généralement en combinaison avec des organes écarteurs (E).In a perfectly known manner, this type of slide results from a smooth assembly (L) in alignment with support posts (P), generally in combination with spreader members (E).
Sous la lisse (L), peu être monté un écran de protection (1) destiné notamment à empêcher les véhicules deux roues et leurs passagers, en cas de chute, de glisser sous la lisse (L) afin, bien évidemment, d'éviter les chocs avec le poteau support (P), étant donné que ces écrans (1) sont disposés devant lesdits poteaux (P).Under the rail (L), can be mounted a protective screen (1) intended in particular to prevent two-wheel vehicles and their passengers, in case of fall, to slide under the rail (L) to, of course, to avoid the shocks with the support post (P), since these screens (1) are arranged in front of said posts (P).
Différentes solutions techniques peuvent être envisagées pour assurer le montage des écrans (1). Très souvent, ces écrans sont fixés, au moyen de bras support (2), à une partie de la lisse (L) en combinaison ou non avec l'écarteur (E) et/ou le poteau (P). De telles dispositions ne sont pas décrites en détail car elles ne font pas partie de l'objet spécifique de l'invention et sont parfaitement connues de l'homme du métier.Various technical solutions can be envisaged for mounting the screens (1). Very often, these screens are fixed, by means of support arms (2), to a portion of the beam (L) in combination or not with the spacer (E) and / or the pole (P). Such arrangements are not described in detail because they are not part of the specific object of the invention and are well known to those skilled in the art.
Selon l'invention, le but recherché est de monter à l'extrémité de l'écran (1) (éventuellement de la lisse (L)), un embout de protection (3) conformé également pour éviter tout contact direct avec le poteau correspondant en faisant office d'élément amortisseur disposé devant ledit poteau considéré dans le sens de circulation.According to the invention, the aim is to mount at the end of the screen (1) (possibly of the rail (L)), a protective cap (3) shaped also to avoid any direct contact with the corresponding pole acting as damping element disposed in front of said pole in the direction of circulation.
Cet embout (3) est avantageusement réalisé à partir d'une plaque préalablement pliée et découpée. Ainsi, cet embout (3) présente une partie d'appui (3a) apte à coopérer avec la section interne de l'écran (1). Autrement dit, le profil en section transversal de la partie (3a) correspond sensiblement eu profil transversal de la section interne de l'écran (1). Cette partie (3a) est prolongée par une forme arrondie (3b) elle-même prolongée par une patte doublement équerrée (3c) pour délimiter, en combinaison avec la forme arrondie, une structure totalement fermée faisant office d'amortisseur disposé devant le poteau (P). La patte doublement équerrée (3c) délimite transversalement une section en U avec une branche commune (3c1), et perpendiculairement à cette dernière, deux ailes latérales (3c2) et (3c3).This tip (3) is advantageously made from a plate previously folded and cut. Thus, this tip (3) has a bearing portion (3a) adapted to cooperate with the internal section of the screen (1). In other words, the cross-sectional profile of the portion (3a) substantially corresponds to the transverse profile of the internal section of the screen (1). This part (3a) is extended by a rounded shape (3b) itself extended by a doubly squared leg (3c) to delimit, in combination with the rounded shape, a totally closed structure acting as a shock absorber arranged in front of the post ( P). The doubly squared leg (3c) delimits transversely a U-shaped section with a common branch (3c1), and perpendicular thereto, two lateral wings (3c2) and (3c3).
L'aile (3c2) prend appui contre une partie de la face interne de la partie (3a) qui coopère avec des moyens d'assemblage (4) engagés dans des trous (3a1) que présente ladite patte (3a) et destinés à assurer sa fixation au niveau de la face interne de l'écran (1). Par exemple, la partie d'appui (3a) présente quatre trous disposés sensiblement selon les sommets d'un carré, pour l'engagement des organes d'assemble (4) sous forme de boulons traversant l'épaisseur de l'écran (1). L'aile (3c2) présente donc des trous en communication avec l'une des séries de trous (3a1) pour l'engagement des organes d'assemblage (4).The wing (3c2) bears against a portion of the inner face of the portion (3a) which cooperates with assembly means (4) engaged in holes (3a1) that has said tab (3a) and intended to ensure its fixing at the inner face of the screen (1). For example, the support portion (3a) has four holes arranged substantially at the vertices of a square, for the engagement of the assembly members (4) in the form of bolts passing through the thickness of the screen (1). ). The wing (3c2) thus has holes in communication with one of the series of holes (3a1) for the engagement of the assembly members (4).
Après fixation de l'embout (3) dans les conditions indiquées, la branche commune de liaison (3c1) de la patte doublement équerrée est située devant le poteau (P) et dans un plan sensiblement parallèle à ce dernier. Cette branche commune peut être en appui ou sensiblement en appui contre la face correspondante du poteau (P).After attachment of the tip (3) under the conditions indicated, the common connecting branch (3c1) of the doubly squared leg is located in front of the pole (P) and in a plane substantially parallel to the latter. This common branch may be supported or substantially supported against the corresponding face of the pole (P).
Dans l'exemple de réalisation illustré aux figures des dessins, la partie d'appui (3a) présente, sensiblement dans sa partie centrale, d'une manière équidistante aux quatre trous (3a1), une lumière oblongue (3a2) pour l'engagement d'au moins un organe de fixation (5) traversant l'épaisseur de l'écran et coopérant avec une lumière (2a) que présente le bras support (2) destiné à assurer la fixation, comme indiqué, de l'ensemble de l'écran (1) par rapport à une partie de la glissière de sécurité.In the exemplary embodiment illustrated in the figures of the drawings, the bearing part (3a) has, substantially in its central part, in a manner equidistant to the four holes (3a1), an oblong slot (3a2) for the engagement at least one fixing member (5) passing through the thickness of the screen and cooperating with a slot (2a) which the support arm (2) has for fixing, as indicated, all the screen (1) with respect to a part of the guardrail.
La partie d'appui et de fixation (3a) de l'embout peut éventuellement être profilée en section, pour coopérer avec la face interne de l'extrémité de la lisse (L) afin d'assurer la même fonction que pour l'écran (1).The support and fixing part (3a) of the end piece may optionally be profiled in section, to cooperate with the inner face of the end of the arm (L) to ensure the same function as for the screen (1).
Les avantages ressortent bien de la description, en particulier on souligne et on rappelle :
- la facilité de réalisation ;
- la facilité de montage par rapport à l'écran, sans nécessiter d'éléments rapportés d'assemblage et, d'une manière indépendante, des poteaux support.
- ease of realization;
- ease of assembly relative to the screen, without the need for assembly inserts and, independently, support posts.
