Description
L'invention concerne un dispositif formant écran antiéblouissant.The invention relates to a device forming an anti-dazzle screen.
Il existe de nombreuses réalisations de tels dispositifs.There are many embodiments of such devices.
Parmi ceux-ci, on pourra relever en particulier les écrans destinés à venir reposer au niveau de la partie supérieure d'un muret séparateur de voies de circulation, du type constitué d'au moins un panneau comprenant, formé d'une seule pièce en matière plastique, une base de positionnement surmontée d'une plaque déflectrice sensiblement verticale dont l'un des chants longitudinaux s'étend dans le prolongement de l'axe médian vertical dudit muret.Among these, we can note in particular the screens intended to come to rest at the level of the upper part of a wall separating traffic lanes, of the type consisting of at least one panel comprising, formed in one piece by plastic material, a positioning base surmounted by a substantially vertical deflecting plate, one of the longitudinal edges of which extends in the extension of the vertical median axis of said wall.
De tels dispositifs connus sont parfois difficiles à réaliser industriellement et présentent en général un coût de fabrication élevé. De plus, certains d'eux sont instables après qu'ils aient été mis en position sur les séparateurs de voies destinés à les recevoir.Such known devices are sometimes difficult to produce industrially and generally have a high manufacturing cost. In addition, some of them are unstable after they have been placed in position on the channel dividers intended to receive them.
Par ailleurs, de tels écrans n'étant pas toujours fixés ou scellés en position, cela rend relativement aisé leur déplacement ou leur enlèvement non autorisé, entraînant par là même d'éventuels risques d'accidents, notamment lorsque ces écrans sont disposés de long de voies de circulation autoroutières.Furthermore, since such screens are not always fixed or sealed in position, this makes their movement or their unauthorized removal relatively easy, thereby causing possible risks of accidents, in particular when these screens are arranged along the length of the screen. motorway traffic lanes.
On notera également que la plupart des écrans antiéblouissants connus, s'ils sont parfois juxtaposables, ne sont en général pas superposables, ce qui les rend plus difficiles à adapter à la hauteur de protection désirée.It will also be noted that most of the known anti-dazzle screens, if they are sometimes juxtaposable, are generally not superimposable, which makes them more difficult to adapt to the desired protection height.
La présente invention a pour but de remédier à ces inconvénients.The present invention aims to remedy these drawbacks.
A cet effet, et en particulier de manière à améliorer l'effet d'occultation des panneaux, la plaque déflectrice comprend une succession de pans formés selon une ligne directrice brisée orientée, d'une façon générale, sensiblement dans l'axe du chant longitudinal de la plaque.To this end, and in particular so as to improve the screening effect of the panels, the deflector plate comprises a succession of sections formed along a broken guideline oriented, generally, substantially in the axis of the longitudinal edge of the plate.
De préférence, les pans de la plaque déflectrice seront liés entre-eux à la suite les uns des autres, par série, chaque série comprenant successivement :
- un premier pan opaque sensiblement parallèle au chant précité de la plaque,
- un second pan également opaque dirigé obliquement en faisant un angle obtus avec l'axe dudit chant,
- un troisième pan opaque sensiblement parallèle à l'axe de ce même chant,
- puis un quatrième pan dirigé obliquement en faisant un angle également obtus avec l'axe dudit chant, ce quatrième pan comprenant au moins une fenêtre assurant le libre passage de la lumière et/ou du vent.Preferably, the sides of the deflector plate will be linked to one another following each other, by series, each series successively comprising:
- a first opaque pan substantially parallel to the aforementioned edge of the plate,
- a second also opaque pan directed obliquely at an obtuse angle with the axis of said edge,
- a third opaque pan substantially parallel to the axis of this same edge,
- Then a fourth section directed obliquely at an angle also obtuse with the axis of said edge, this fourth section comprising at least one window ensuring the free passage of light and / or wind.
En pratique, l'écran de l'invention sera habituellement constitué de plusieurs panneaux justaposables sensiblement parallélépipèdiques et de forme générale plane.In practice, the screen of the invention will usually be made up of several coverable panels which are substantially parallelepipedic and of generally planar shape.
Ainsi, de manière qu'une fois placés sur leur muret récepteur les panneaux puissent y être maintenus en toute sécurité, une autre caractéristique de l'invention prévoit que chaque panneau comprendra, formés sensiblement dans son plan et vers ses extrémités opposées de jonction avec un panneau adjacent, des prolongements en saillie et des dégagements en retrait formant respectivement redans et créneaux de manière que les redans de l'un des panneaux puissent venir s'engager dans les créneaux d'un panneau juxtaposé adjacent, et, dans chaque redan desdits panneaux, sera ménagé un orifice traversant, dans lequel pourra venir s'engager verticalement une barre destinée à assurer la jonction de deux panneaux adjacents ainsi que la fixation desdits panneaux sur le muret en venant par son extrémité inférieure se loger et se verrouiller dans un trou récepteur ménagé dans le rebord supérieur dudit muret.Thus, so that once placed on their receiving wall the panels can be kept there safely, another characteristic of the invention provides that each panel will comprise, formed substantially in its plane and towards its opposite ends of junction with a adjacent panel, projecting extensions and recessed recesses respectively forming steps and slots so that the steps of one of the panels can engage in the slots of an adjacent juxtaposed panel, and, in each step of said panels , will be formed a through hole, in which can come vertically engage a bar intended to ensure the junction of two adjacent panels as well as the fixing of said panels on the wall by coming by its lower end to be housed and locked in a receiving hole formed in the upper edge of said wall.
Selon encore une autre caractéristique de l'invention, les panneaux formant l'écran seront superposables, la base de positionnement de chaque panneau comprenant une découpe intérieure ayant en section l'aspect d'une rigole inversée dont la forme correspondra sensiblement à celle du bord supérieur de la plaque déflectrice, de manière que la rigole d'un panneau supérieur puisse venir chevaucher le bord supérieur d'un panneau inférieur.According to yet another characteristic of the invention, the panels forming the screen will be superimposable, the positioning base of each panel comprising an interior cutout having in section the appearance of an inverted channel whose shape will correspond substantially to that of the edge. upper of the deflector plate, so that the channel of an upper panel can overlap the upper edge of a lower panel.
D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement de la description qui va suivre faite en référence aux dessins d'accompagnement présentés à titre d'exemple non limitatif et dans lesquels :

Si l'on se reporte tout d'abord à la figure 1, on voit, repéré dans son ensemble 1, un dispositif formant écran antiéblouissant prévu notamment pour occulter la lumière des phares des véhicules se déplaçant en sens inverses sur des voies de circulation, routière ou autoroutière, le long desquelles a été disposé l'écran de l'invention.If we refer first to FIG. 1, we see, identified as a whole 1, a device forming an anti-dazzle screen intended in particular to obscure the light of the headlights of vehicles moving in opposite directions on traffic lanes, road or motorway, along which was arranged the screen of the invention.
L'écran illustré comprend, réalisé d'une seule pièce en matière plastique moulée,une base de positionnement 2 relativement large (d) ayant en section la forme d'un "U" inversé, au-dessus de laquelle s'étend sensiblement verticalement une plaque 3 déflectrice de largeur plus réduite. Cette plaque 3 a une forme générale de parallélépipède rectangle sensiblement plane, orientée de manière que son chant longitudinal inférieur 3a soit situé sensiblement dans le prolongement de l'axe vertical 4a médian d'un muret 4 séparateur unique de voies de circulation, muret sur lequel sera alors positionné l'écran (Figures 1 et 2).The screen illustrated comprises, made in a single piece of molded plastic, a relatively wide positioning base 2 (d) having in section the shape of an inverted "U", above which extends substantially vertically. a
Tel qu'il ressort clairement de la figure 1, la base 2 de l'écran vient reposer au niveau de l'extrémité 200 de ses branches du "U" entièrement sur le rebord supérieur 40 du muret 4.As is clear from FIG. 1, the
Bien que le rebord 40 du muret ait été représenté sensiblement horizontal, on pourraît éventuellement prévoir un muret présentant une autre forme, tel qu'un rebord à forme convexe.Although the
Le rebord 40 présentera donc une largeur D supérieure ou à la limite égale à celle d de la base 2 de l'écran.The
Figure 1, on remarquera que la base 2,compte-tenu de sa section en "U" inversé, comprend une découpe intérieure 5 en forme de rigole. De préférence, cette rigole 5 comprendra un double épaulement 6, élargissant la rigole vers son extrémité inférieure débouchante.Figure 1, it will be noted that the
Conformément à l'invention, l'écran que l'on vient de présenter est en fait constitué de plusieurs panneaux indentiques juxtaposables et superposables.According to the invention, the screen that has just been presented is in fact made up of several identical panels which can be juxtaposed and stacked.
Sur les différentes figures, les panneaux formant l'écran ont tous été repérés par 1ʹ.In the various figures, the panels forming the screen have all been marked with 1ʹ.
On comprendra donc qu'à la figure 1 est en fait illustré un panneau 1ʹ⊄ pouvant constituer l'un des éléments de l'écran de l'invention.It will therefore be understood that in FIG. 1 is in fact illustrated a panel 1ʹ⊄ which can constitute one of the elements of the screen of the invention.
De façon à assurer la superposition de deux panneaux et permettre un emboîtement ou un chevauchement partiel de la base d'un panneau dit "supérieur" autour de la bordure de sommet d'un panneau sous-jacent, on prévoit que la rigole 5 comprend un fond 7 de rigole de largeur dʹ sensiblement égal ou légèrement supérieur à la largeur dʺ de la partie extrême ou bordure de sommet 30 de la plaque 3.In order to ensure the superposition of two panels and allow a partial nesting or overlapping of the base of a so-called "upper" panel around the top edge of an underlying panel, it is provided that the channel 5 comprises a
En d'autres termes, on prévoit que le profil en section de la rigole 5 présente une forme correspondant sensiblement à celle de la bordure supérieure de la plaque du panneau sur laquelle elle doit s'emboîter.In other words, provision is made for the sectional profile of the channel 5 to have a shape corresponding substantially to that of the upper edge of the panel plate on which it must fit.
Afin d'assurer une bonne stabilité à l'emboîtement partiel ainsi réalisé, on peut prévoir, sur une partie au moins de la longueur L hors tout d'un panneau et légèrement en-dessous du sommet 31 de la plaque 3, deux nervures 8 ou ailes latérales saillantes s'étendant des faces opposées de cette plaque, sensiblement au même niveau.In order to ensure good stability for the partial nesting thus produced, two
Dans ce cas, lors de l'emboîtement de deux panneaux, chaque extrémité 200 de la rigole 5 d'un panneau "supérieur" viendra, comme on le comprend, reposer sur l'une des nervures 8.In this case, during the interlocking of two panels, each
On notera que ces nervures 8 jouent également le rôle de rigidificateurs de la plaque 3. Aussi, pourraît-on éventuellement en prévoir d'autres, tel que 8ʹ, réparties d'endroit en endroit le long de la plaque.It will be noted that these
Pous assurer l'assemblage de plusieurs panneaux juxtaposés en alignement, on notera figure 2 et plus précisément figure 4, que chaque panneau 1ʹ comprend latéralement vers ses extrémités opposées de jonction avec un panneau adjacent, d'un côté des prolongements 12a, 12b et dégagement 22a, et,de l'autre, des dégagements 23a, 23b et prolongement 13a, complémentaires des premiers.To ensure the assembly of several panels juxtaposed in alignment, it will be noted in FIG. 2 and more precisely in FIG. 4, that each panel 1ʹ comprises laterally towards its opposite ends of junction with an adjacent panel, on one side of the extensions 12a, 12b and
On notera que les prolongements et dégagements précités de chaque panneau sont formés sensiblement dans la direction du plan général 9 du panneau.It will be noted that the aforementioned extensions and clearances of each panel are formed substantially in the direction of the
Si l'on se reporte maintenant de façon plus spécifique à la figure 2, on voit que l'extrémité repérée 10 des panneaux pourra en particulier comprendre deux prolongements 12a, 12b ou pattes saillantes écartées l'une de l'autre le long de la bordure extrême 10a et formant redans. Entre-eux, ces redans ménageront un dégagement 22a en retrait formant créneau.If we now refer more specific to FIG. 2, it can be seen that the end marked 10 of the panels may in particular comprise two extensions 12a, 12b or projecting legs spaced from one another along the
A l'opposé, vers leur autre extrémité repérée 11, les panneaux comprendront alors deux dégagements 23a, 23b, complémentaires formant créneaux, entre lesquels sera intercalé un prolongement complémentaire en redan 13a.In contrast, towards their other end marked 11, the panels will then comprise two
Comme il ressort clairement de la figure 4 et comme on le comprend, les dégagements 23a, 23b, et le prolongement 13a complémentaires prévus vers une extrémité 11, correspondent sensiblement aux prolongements 12a, 12b et au dégagement 22a prévus vers l'autre extrémité 10, et sont formés sensiblement à leur niveau.As is clear from FIG. 4 and as can be understood, the
De façon à assurer une solidarisation étroite des panneaux au niveau de ces formes complémentaires qui s'imbriquent sensiblement les unes dans les autres lors de la juxtaposition de plusieurs panneaux, on prévoit de ménager, dans chaque prolongement ou redan 12a, 12b, 13a et vers les deux extrémités opposées 10, 11 de chaque panneau, des orifices 14, 15, d'axe sensiblement vertical en position d'utilisation du panneau, ces orifices pouvant être traversés par une barre 16 rigide de liaison.In order to ensure a close connection of the panels at the level of these complementary shapes which substantially overlap one another during the juxtaposition of several panels, provision is made to provide, in each extension or step 12a, 12b, 13a and towards the two
Cette barre 16 a été représentée en trait mixte aux figures 1, 2 et 4.This
Afin de fixer la position des panneaux 1ʹ sur le muret séparateur 4 au-dessus duquel ils doivent être mis en place, la partie extrême inférieure 17 de chaque barre 16 viendra se loger et se verrouiller dans un trou récepteur 18 prévu en regard dans le rebord supérieur du muret 4, après avoir traversé les orifices 14, 15 correspondants.In order to fix the position of the panels 1ʹ on the separating
Le verrouillage de la barre 16 pourra notamment être assuré par un scellement ou un vissage de sa partie extême 17 dans le muret.The locking of the
Si l'on se reporte maintenant à la figure 3, on voit que les trous 14, 15, formés vers chaque extrêmité 10, 11 des panneaux ont, de préférence, en section horizontale une forme sensiblement oblongue ou ovale, la barre 16 étant, quant à elle, sensiblement cylindrique à section circulaire.If we now refer to Figure 3, we sees that the
De cette façon, on pourra articuler, si nécessaire, les panneaux entre-eux de façon à suivre le profil du muret.In this way, we can articulate, if necessary, the panels together so as to follow the profile of the wall.
Sur cette même figure 3 est également illustrée la forme en section de la plaque déflectrice 3 du panneau, laquelle comprend une succession de pans 19, 20, 21, 22 (seuls certains des pans ont été repérés) formés selon une ligne directrice brisée ou "ondulée", dont la ligne générale reste dans la direction du plan 9.In this same FIG. 3 is also illustrated the sectional shape of the
Les pans illustrés qui sont liés les uns aux autres et s'étendent sensiblement verticalement en position d'utilisation du panneau, pratiquement sur toute la hauteur de la plaque 3, sont formés en séries, chaque série comprenant, qui se suivent dans l'ordre :
- un premier pan 19 formé sensiblement dans le plan du panneau c'est-à-dire dans la direction de circulation des véhicules cheminant le long de l'écran (les deux sens opposés de circulation ont été représentés par les flèches 23, 24),
- puis, un deuxième pan 20 oblique par rapport au panneau et donc à la direction de circulation et offrant un angle ϑ obtus par rapport au sens de déplacement condidéré (par exemple 23),
- suivi d'un troisième pan 21 ici décalé latéralement de la même distance dʺʹ de l'axe médian longitudinal 9ʹ du panneau que le pan 19, le pan 21 étant formé, comme ce pan 19, sensiblement parallèlement à la direction de circulation ;
- et enfin un quatrième pan 22 dirigé de façon oblique par rapport à la direction de circulation, le pan 22 offrant un angle β obtus par rapport au sens de circulation suivis par les véhicules.The illustrated panels which are linked to each other and extend substantially vertically in the position of use of the panel, practically over the entire height of the
- A
- then, a
- followed by a
- And finally a
On notera, que, dans l'exemple illustré, l'angle γ supplémentaire de β est tel que γ inférieur ou égal à α (en valeur obsolue), α étant l'angle supplémentaire de β.It will be noted that, in the example illustrated, the additional angle γ of β is such that γ less than or equal to α (in obsolete value), α being the additional angle of β.
Compte tenu du sens de déplacement prévu des véhicules, on prévoira avantageusement que les pans 22, qui ne reçoivent pas directement les rayons lumineux issus des phares avant de ces mêmes véhicules seront en fait constitués,de préférence sur la plus grande partie de leur hauteur,par une fenêtre laissant librement passer la lumière et le vent. Tel qu'on le voit figure 2, on pourrait également prévoir de ménager dans les pans 22, plusieurs ouvertures 220 formant fenêtres séparées par des bandes horizontales 221 ménageant des points rigides de liaison intermédiaires des pans 19 et 21 entre-eux.Taking into account the intended direction of movement of the vehicles, provision will advantageously be made for the
Par contre, les pans 20 d'occultation seront des pans pleins opaques, de même que les pans 19 et 21.On the other hand, the
De cette façon, les rayons lumineux issus des phares avant des véhicules seront en quelque sorte piégés, soit au niveau des pans 19 et 20 dans le sens 23 de circulation, soit au niveau des pans 20 et 21 dans le sens 24 contraire de circulation.In this way, the light rays coming from the front headlights of the vehicles will be in some way trapped, either at the
On notera que les rayons lumineux ne pourront traverser la fenêtre 22 ou les ouvertures 220 que s'ils s'écartent de la direction de circulation d'un angle supérieur à γ et ne rencontrent pas les pans 21, 20, 19.It will be noted that the light rays can only pass through the
A titre d'exemples, on pourra prévoir pour les pans 20 et 22, des angles α et γ tel que α = 45° environ et γ = 30° environ, soit ϑ et β de l'ordre de 135° et 150° respectivement.By way of examples, it will be possible for the
En outre parallèlement à la direction de circulation, c'est-à-dire dans le plan 9 des panneaux, la longueur L₁ des pans 22 à fenêtres pourra notamment être prévue sensiblement égale à celle L₂ des trois panneaux opaques consécutifs 19, 20, 21, voir même inférieure.In addition parallel to the direction of circulation, that is to say in the
Concernant le mode de fabrication de l'écran de l'invention, on notera que chaque panneau pourra être réalisé en polyéthylène haute densité par moulage, de même que la barre 16 de liaison des panneaux entre-eux. Une barre métallique pourrait toutefois également convenir.Regarding the method of manufacturing the screen of the invention, it will be noted that each panel can be made of high density polyethylene by molding, as well as the
Concernant les prolongements et dégagements formés vers les extrémités de jonction de chacun des panneaux, on pourraît, à titre de variante, et comme on le comprend, prévoir un plus grand nombre de prolongements formant redans et donc un plus grand nombre de dégagements formant créneaux en adaptant de façon convenable leur disposition relative.As regards the extensions and clearances formed towards the junction ends of each of the panels, we could, as a variant, and as we understand, provide a greater number of extensions forming steps and therefore a greater number of clearances forming slots in suitably adapting their relative arrangement.
Si l'on se reporte maintenant à la figure 5, on voit illustré un moyen complémentaire de fixation des panneaux sur le muret, de manière à prévenir tous risques de chute en cas de rupture des attaches de liaison des panneaux juxtaposés entre-eux.If we now refer to FIG. 5, we see illustrated an additional means of fixing the panels to the wall, so as to prevent any risk of falling in the event of breakage of the connecting clips of the panels juxtaposed between them.
Ce moyen complémentaire prend ici la forme d'une tige d'ancrage 25 verticale propre à venir se loger étroitement dans un orifice 26 de réception ménagé en regard sensiblement dans l'axe médian 4a du muret et débouchant sur le rebord supérieur 40 de celui-ci. En partie supérieure, la tige 25 se prolonge par une tête 27, ayant par exemple la forme d'un profilé en "U" venant s'engager dans la rigole 7 de la base 2 du panneau sur les flancs de laquelle la tête en question sera fixée, par exemple par rivetage, vissage ou analogue.This complementary means here takes the form of a
De préférence, le moyen complémentaire de fixation sera placé sensiblement à mi-longueur (L/2) de chaque panneau et donc a peu près à équidistance de deux barres 16 successives de maintien.Preferably, the additional fixing means will be placed substantially at mid-length (L / 2) of each panel and therefore approximately equidistant from two successive holding bars 16.
