Description

La présente invention concerne un écran anti-­éblouissement destiné notamment à séparer les voies de circulation routières pour éviter que les feux d'é­clairage des véhicules circulant dans une direction, n'éblouissent ou ne fatiguent les conducteurs des vé­hicules venant dans la direction inverse.The present invention relates to an anti-dazzle screen intended in particular to separate the road traffic lanes to prevent the lights of vehicles traveling in one direction, from dazzling or tiring the drivers of vehicles coming in the opposite direction.

Il existe différents types d'écrans anti-­éblouissement. En général, ces écrans sont fixés sur la barrière centrale de séparation et se composent des lames verticales, inclinées pour séparer les deux voies de circulation de manière opaque pour les con­ducteurs regardant devant eux tout en constituant une barrière transparente lorsqu'on regarde dans une di­rection transversale.There are different types of anti-glare screens. In general, these screens are fixed on the central separation barrier and consist of vertical slats, inclined to separate the two traffic lanes in an opaque manner for drivers looking ahead while constituting a transparent barrier when looking in one direction. transverse.

Ces écrans anti-éblouissement connus présentent un certain nombre d'inconvénients liés à leur structu­re discontinue, à la nécessité qu' il y a de fixer les éléments séparément sur la barrière centrale ou de constituer des dispositifs en forme de peigne sur les­quels sont fixées les lames, et les dispositifs eux-­mêmes sont mis en place entre les deux voies.These known anti-glare screens have a certain number of drawbacks linked to their discontinuous structure, to the need to fix the elements separately on the central barrier or to form comb-shaped devices on which the blades, and the devices themselves are put in place between the two tracks.

La complexité de la réalisation de ces disposi­tifs se traduit par un coût correspondant élevé.The complexity of producing these devices translates into a corresponding high cost.

La présente invention a pour but de remédier aux inconvénients des dispositifs connus et se propose de créer un écran anti-éblouissement qui soit d'une ré­ alisation simple et peu coûteuse, d' un encombrement réduit avant sa mise en place et qui, une fois mis en place, constitue un écran anti-éblouissement efficace.The present invention aims to remedy the drawbacks of known devices and proposes to create an anti-glare screen which is of a re simple and inexpensive installation, of a reduced size before its installation and which, once installed, constitutes an effective anti-glare screen.

A cet effet, l'invention concerne un écran anti-­éblouissement caractérisé en ce qu'il est formé à par­tir d'une bande, la bande étant munie d'entailles is­sues du bord "supérieur" et d'entailles issues du bord "inférieur", ces entailles ne s'étendant pas sur toute la largeur de la bande,
- les entailles issues du bord supérieur et cel­les issues du bord inférieur se suivant en alternance pour former des branches dans l'intervalle de deux en­tailles successives, des parties "supérieures" de liaison entre deux entailles successives issues du bord "supérieur" et au-dessus de l'entaille intermé­diaire issue du bord "inférieur" et reliant chaque fois les extrémités correspondantes de deux branches successives,
- des parties inférieures de liaison entre deux entailles successives issues du bord inférieur et en-­dessous de l'entaille intermédiaire issue du bord supérieur, les parties inférieures étant au moins par­tiellement rabattables pour former chaque fois une patte d'appui et de fixation de l'écran sur un support,
- la bande munie des entailles se déployant à la pose dans la direction de mise en place pour ouvrir les branches autour de l'articulation respective for­mée chaque fois par la partie supérieure et la partie inférieure reliant deux branches successives pour écarter ces branches et les incliner les unes par rap­port aux autres et disposer leur surface en biais par rapport à la ligne de pose pour former un écran opaque dans la direction longeant l'écran.
To this end, the invention relates to an anti-glare screen characterized in that it is formed from a strip, the strip being provided with notches coming from the "upper" edge and notches coming from the "lower" edge ", these cuts not extending over the entire width of the strip,
- the notches from the upper edge and those from the lower edge alternate to form branches in the interval of two successive notches, "upper" connecting parts between two successive notches from the "upper" edge and- above the intermediate notch coming from the "lower" edge and each time connecting the corresponding ends of two successive branches,
- lower connecting parts between two successive notches coming from the lower edge and below the intermediate notch coming from the upper edge, the lower parts being at least partially foldable to each time form a support and fixing lug for the screen on a support,
- the strip provided with the notches deploying on laying in the direction of installation to open the branches around the respective joint formed each time by the upper part and the lower part connecting two successive branches to spread these branches and tilt them relative to each other and arrange their surface at an angle to the laying line to form an opaque screen in the direction along the screen.

Cet écran est réalisé à partir d'une bande par des entailles alternées partant de ses deux bords. Cette fabrication est particulièrement simple. Le stockage d'une telle bande peut également se faire simplement sous la forme d'un rouleau dont la longueur enroulée dépend du poids de la matière constituant la bande, de façon que les rouleaux puissent être manu­tentionnés facilement. Ces rouleaux se transportent également facilement sur le lieu de la mise en place de l'écran anti-éblouissement. A cet endroit, il suf­fit de dévider le rouleau, par exemple embarqué à bord d'un camion, pour le fixer de manière continue par exemple sur la barrière de séparation médiane des voies de circulation. La mise en place se fait très simplement. Il suffit de clouer ou de fixer de manière analogue les pattes rabattues à la base des parties inférieures de la liaison entre chaque fois deux branches. L'inclinaison des pattes se règle automati­quement en fonction du pas que l'on a choisi pour l'écran.This screen is produced from a strip by alternating cuts starting from its two edges. This manufacturing is particularly simple. The storage of such a strip can also be done simply in the form of a roll, the wound length of which depends on the weight of the material constituting the strip, so that the rolls can be handled easily. These rollers are also easily transported to the place of installation of the anti-glare screen. At this point, it is sufficient to unwind the roll, for example on board a truck, to fix it continuously, for example on the median separation barrier of the traffic lanes. The installation is done very simply. It suffices to nail or to fix in a similar manner the legs folded down at the base of the lower parts of the connection between each time two branches. The inclination of the legs is automatically adjusted according to the pitch that has been chosen for the screen.

Le remplacement partiel d'un tel écran anti-­éblouissement se fait avec la même facilité pour la partie détruite ou abîmée par exemple en cas d'accident.The partial replacement of such an anti-glare screen is done with the same ease for the destroyed or damaged part, for example in the event of an accident.

Suivant une autre caractéristique de l'invention, la partie haute est constituée par un bourrelet.According to another characteristic of the invention, the upper part is constituted by a bead.

Ce bourrelet qu constitue en totalité ou en par­tie la partie haute forme une articulation et une ex­trémité supérieure renforcée reliant les deux branches et leur donnant une certaine tenue tout en permettant l'ouverture des deux branches.This bead that constitutes all or part of the upper part forms a joint and a reinforced upper end connecting the two branches and giving them a certain hold while allowing the opening of the two branches.

Suivant une autre caractéristique, les entailles se terminent par une ouverture arrondie.According to another characteristic, the notches end in a rounded opening.

Grâce à cette ouverture arrondie qui termine cha­que entaille, on évite que l'entaille ne progresse au-­delà de l'ouverture et ne fragilise la partie infé­ rieure ou supérieure constituant l'articulation en créant une zone fragile de rupture préférentielle.Thanks to this rounded opening which ends each notch, it is avoided that the notch progresses beyond the opening and does not weaken the lower part superior or superior constituting the articulation by creating a fragile preferential rupture zone.

Suivant une autre caractéristique de l'invention, la bande est obtenue par extrusion. Ce procédé de fa­brication est particulièrement pratique quel que soit le profil de la bande en particulier si comme indiqué ci-dessus la partie supérieure est constituée par un bourrelet et si comme précisé, suivant une autre ca­ractéristique de l'invention, la partie inférieure formant l'appui est réalisée pliée au moment de l'ex­trusion de la bande, l'angle de pliage pouvant être un angle de 90° ou de préférence égal à l'angle d'incli­naison des branches (c'est-à-dire correspondant au pas) une fois l'écran déployé et fixé.According to another characteristic of the invention, the strip is obtained by extrusion. This manufacturing process is particularly practical regardless of the profile of the strip, in particular if, as indicated above, the upper part is constituted by a bead and if, as specified, according to another characteristic of the invention, the lower part forming the 'support is made folded at the time of extrusion of the strip, the folding angle can be an angle of 90 ° or preferably equal to the angle of inclination of the branches (that is to say corresponding to the step) once the screen is deployed and fixed.

La présente invention sera décrite de manière plus détaillée à l'aide des dessins annexés dans les­quels :

  • - la figure 1 est une vue en plan d'un exemple de réalisation d'une bande d'écran anti-éblouissement selon l'invention,
  • - la figure 2 est une vue en perspective d'un autre exemple de réalisation d'une bande d'écran anti-­éblouissement selon l'invention,
  • - la figure 3 est une vue en perspective de la bande de la figure 2 après installation sur une barrière.
The present invention will be described in more detail with the aid of the appended drawings in which:
  • FIG. 1 is a plan view of an exemplary embodiment of an anti-dazzle screen strip according to the invention,
  • FIG. 2 is a perspective view of another exemplary embodiment of an anti-dazzle screen strip according to the invention,
  • - Figure 3 is a perspective view of the strip of Figure 2 after installation on a barrier.

Selon la figure 1, l'écran anti-éblouissement se­lon l'invention, se compose d'une bande portant globa­lement la référence 1. Cette bande comporte un bord supérieur "2" et un bord inférieur "3". Les expres­sions "supérieur" et "inférieur" ont été choisies en fonction de l'utilisation et de la mise en place de la bande. Il s'agit seulement d'une convention.According to FIG. 1, the anti-dazzle screen according to the invention, is composed of a strip generally bearing the reference 1. This strip has an upper edge "2" and a lower edge "3". The expressions "upper" and "lower" were chosen according to the use and the positioning of the strip. It is only a convention.

La bande comporte des entailles 4 issues du bord supérieur 2 et des entailles 5 issues du bord infé­rieur 3. Les entailles 4 et 5 ne s'étendent pas sur toute la largeur L de la bande mais s'arrêtent à une certaine distance du bord opposé. Ainsi, les entailles 4 issues du bord supérieur 2 s'arrêtent sur une ligne 6 et les entailles 5 issues du bord inférieur 3 s'ar­rêtent sur une ligne 7. Les entailles 4 et 5 se sui­vent en alternance et forme ainsi les différentes par­ties constitutives de l'écran anti-éblouissement, à savoir :
- les entailles 4 et 5 successives forment dans leur intervalle des branches 8 comprises entre les deux lignes 6 et 7,
- entre deux entailles successives 4, 4, issues du bord supérieur 2, on a une partie "supérieure" 9 de liaison au-dessus de l'extrémité de l'entaille inter­médiaire 5 issue du bord inférieur 3. Cette partie su­périeure 9 relie chaque fois l'extrémité supérieure de deux branches successives 8.
- entre deux entailles 5 issues du bord inférieur et en-dessous de l'extrémité inférieure de l'entaille 4 intermédiaire issue du bord supérieur 2, on a une partie inférieure 10 entre le bord inférieur 3 et la ligne 6. Cette partie inférieure 10 peut être, le cas échéant, subdivisée par une ligne de pliage 11 de fa­çon à former près du bord 3 une patte 12 susceptible d'être rabattue partiellement et servant de patte d'appui et de fixation pour la mise en place de la bande après déploiement, comme écran anti-­éblouissement.
The strip includes notches 4 from the upper edge 2 and notches 5 from the lower edge 3. The notches 4 and 5 do not extend over the entire width L of the strip but stop at a certain distance from the opposite edge. Thus, the notches 4 from the upper edge 2 stop on a line 6 and the notches 5 from the lower edge 3 stop on a line 7. The notches 4 and 5 follow each other alternately and thus form the different constituent parts of the anti-glare screen, namely:
the successive notches 4 and 5 form in their interval branches 8 lying between the two lines 6 and 7,
- Between two successive notches 4, 4, coming from the upper edge 2, there is an "upper" connecting part 9 above the end of the intermediate notch 5 coming from the lower edge 3. This upper part 9 connects each times the upper end of two successive branches 8.
- Between two notches 5 from the lower edge and below the lower end of the intermediate notch 4 from the upper edge 2, there is a lower part 10 between the lower edge 3 and the line 6. This lower part 10 may, where appropriate, be subdivided by a fold line 11 so as to form, near the edge 3, a tab 12 capable of being partially folded down and serving as a support and fixing tab for the positioning of the strip after deployment, as anti-glare screen.

La bande ainsi fabriquée peut être enroulée et fournie au lieu de la mise en place des rouleaux qui sont alors dévidés. Pour déployer la bande qui a ainsi un profil de grecque ou de créneaux, on tire sur celle-ci dans la direction de la flèche A de manière à faire pivoter les branches 8 hors du plan de la bande et les déployer en ouvrant les branches autour de l'articulation à chaque extrémité, formée par la par­tie supérieure et la partie inférieure. On obtient ainsi une disposition telle que celle de la figure 3.The strip thus produced can be rolled up and supplied instead of placing the rollers which are then unwound. To deploy the band which thus has a Greek or niche profile, it is pulled on it in the direction of the arrow A so as to rotate the branches 8 out of the plane of the band and deploy them by opening the branches around of the joint at each end, formed by the upper part and the lower part. An arrangement such as that of FIG. 3 is thus obtained.

La figure 2 montre une forme particulière de ban­de avant déploiement. Cette bande 100 a une section en forme de L avec une partie principale 101 et une par­tie 102 sensiblement perpendiculaire à la partie principale. En haut, elle comporte un bourrelet 103. Des entailles 104, 105, issues respectivement du bord supérieur (c'est-à-dire de celui comportant le bourre­let 103 et du bord inférieur c'est-à-dire celui com­portant la patte 102) alternent successivement pour former les branches 105 et les pattes 106.Figure 2 shows a particular form of strip before deployment. This strip 100 has an L-shaped section with a main part 101 and a part 102 substantially perpendicular to the main part. At the top, it includes a bead 103. Notches 104, 105, respectively coming from the upper edge (that is to say from that comprising the bead 103 and from the lower edge, that is to say that comprising the tab 102 ) alternate successively to form the branches 105 and the legs 106.

Comme indiqué ci-dessus, la partie inférieure 102 formant les pattes 106 peut faire avec la partie 101 un angle différent de 90° et de préférence un angle correspondant à la disposition des branches 105 après déploiement. Cet angle dépend du pas choisi.As indicated above, the lower part 102 forming the legs 106 can make with the part 101 an angle different from 90 ° and preferably an angle corresponding to the arrangement of the branches 105 after deployment. This angle depends on the step chosen.

La bande peut être obtenue par extrusion d'une matière synthétique choisie en fonction des conditions d'utilisation, etc ...The strip can be obtained by extrusion of a synthetic material chosen according to the conditions of use, etc.

Cette bande peut également être, le cas échéant, en métal.This strip can also be, if necessary, made of metal.

Enfin, il convient de souligner que les entailles se terminent à chaque fois par une partie arrondie 13, 107 qui évite que l'entaille ne progresse au-delà de la dimension prévue et qu'elle ne se poursuive par une déchirure fragilisant la liaison entre deux branches successives.Finally, it should be emphasized that the notches end each time with a rounded part 13, 107 which prevents the notch from progressing beyond the dimension provided and that it does not continue with a tear weakening the connection between two successive branches.

La disposition de la bande dépend du sens de cir­culation (à droite ou à gauche) : cela se fait simple­ment par la manière de déployer la bande dans un sens ou dans l'autre.The layout of the strip depends on the direction of traffic (right or left): this is done simply by the way of deploying the strip in one direction or the other.

Il convient de remarquer que la mise en place de la bande sur une glissière centrale en béton se fait sans difficulté particulière.It should be noted that the positioning of the strip on a central concrete slide is done without any particular difficulty.

Dans le cas de glissières formées par des rails, il peut être nécessaire de prévoir un support horizontal, par exemple, une lame qui pourra être, éventuellement, munie d'emplacements prédéterminés, pour recevoir les pattes de fixation. Cette lame pour­ra être en métal mais aussi en une matière synthétique appropriée. Les emplacements prédéterminés peuvent être de légères cavités mais aussi des fentes à tra­vers lesquelles on fait passer les pattes avant de les fixer.In the case of slides formed by rails, it may be necessary to provide a horizontal support, for example, a blade which may possibly be provided with predetermined locations, to receive the fixing lugs. This blade may be made of metal but also of an appropriate synthetic material. The predetermined locations may be slight cavities but also slots through which the legs are passed before fixing them.
