Definitions

  • 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.
  • anti-glare screens 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.
  • 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.
  • 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
  • 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.
  • the upper part is constituted by a bead.
  • 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.
  • the notches end in a rounded opening.
  • 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.
  • the anti-dazzle screen 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.
  • 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.
  • 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, -
  • This upper part 9 connects each times the upper end of two successive branches 8.
  • a lower part 10 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.
  • 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.
  • FIG. 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.
  • 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.
  • the strip can be obtained by extrusion of a synthetic material chosen according to the conditions of use, etc.
  • This strip can also be, if necessary, made of metal.
  • 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.
  • 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.
  • 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.
