   On connaît différents types de barrières de sécurité destinées à em- pêcher les accidents dûs notamment au dérapage des véhicules automobiles, depuis les barrières en bois jusqu'aux barrières en métal et aux récentes barrières en béton. 



   La,présente invention est relative à une barrière de ce genre, qui présente notamment par rapport aux barrières en béton l'avantage d'un placement très rapide et par suite permet une grande économie de main d'oeuvre. Cette nouvelle barrière présente en outre l'avantage imposant de ne pas abîmer les vôitures qui butent contre elle. 



   La barrière de sécurité conforme à la présente invention est essen- tellement caractérisée en ce qu'elle est constituée par une suite d'éléments de choc, tels que des rouleaux, montés de manière à pouvoir tourner librement autour de pivots surmontant verticalement une bande de préférence métallique adaptée au profil du sol auquel elle est fixée, de façon que lesdits éléments de choc, en matériau relativement durci, présentent une résistance suffisante aux chocs, tout en freinant en tournant le contact tangentiel des roues du véhicule dévié de sa, route, 
En utilisant des matériaux appropriés pour les éléments de chocs, leurs pivots et la bande de support, une telle barrière présentera une résistance suffisante non seulement aux chocs, mais aux intempéries. 



   Le   dessin   annexé à ce mémoire représente, uniquement à titre d'exem-   ple,   une forme d'exécution d'une barrière de sécurité conforme à l'invention. 



  Dans ce dessin :    Figure 1 est une vue en perspective d'une portion incurvée d'une barrière, non fixée au solo   
Figure 2 est une coupe axiale au travers d'un rouleau de choc, la barrière étant fixée au solo 
Comme le montre le dessin, la barrière nouvelle comprend essentiel- lement une suite plus ou moins longue suivant le terrain d'éléments de choc con- stitués par des rouleaux 1 montés librement autour de pivots 2 surmontant verti- calement une bande métallique 3, elle-même supportée sur le sol par des pieux ou potelets 4 enfoncés dans ce dernier, de manière que la bande 3 s'adapte au profil de la routeo 
Les rouleaux de choc 1 sont en matériau relativement dur de manière à pouvoir résister aux chocs et aux.intempéries, par exemple en caoutchonc ou en matériau syhthétique approprié.

   Ils auront par exemple comme dimensions un dia- mètre de 20 cm pour une hauteur de 22,5 cm; cette hauteur est calculée de ma- nière à ne pas atteindre la carrosserie, ce qui risquerait de l'abîmer. Les rouleaux seront disposés en laissant entre eux un intervalle de 2 centimètres, par exemple, de façon à constituer une surface   continueo   Les pivots 2, de diamè- tre légèrement inférieur à celui des trous forés axialement dans les rouleaux 1, constituent des tiges filetées, qui traversent verticalement la bande 3; ils main- tiennent les rouleaux entre deux rondelles 5, la rondelle supérieure étant serrée par un écrou 6, tandis que la rondelle inférieure prend appui sur la bande   3;1 un   écrou 7 assure la fixation du pivot 2 à sa base.

   Ces pivots et ces rondelles sont   réàlisées,   par exemple, en laiton ou en acier inoxydable. 



   La bande 3 est constituée par un plat, de préférence en acier inoxy- dable, dont les dimensions, pour des rouleaux de choc définis ci-dessus, seront de l'ordre de 20 cm de largeur sur 5 cm d'épaisseur, sans que ceci doive être c considéré comme une limite dans un sens ou dans l'autre. La bande 3 est fixée par tous moyens appropriés: boulons, rivure,   etcµ,   sur des pieux 4 enfoncés dans le sol S (Figo2), de manière   à   assurer à la bande 3 nn ancrage résistant. Ces pieux seront de préférence en béton, mais éventuellement ils pourraient être en métal.

   On comprend, aisément que, grâce à la faculté des rouleaux 1 de tour- ner librement sur leurs pivots 2, les roues des véhicules qui, lors d'un dérapa- ge par exemple, les   rencontrent   soudainement, non seulement seront repoussées, mais seront freinées tangentiellement dans leur avancement et ramenées sur la rou- te. 



   On notera également que, par suite des dimensions très réduites des rouleaux 1, la piste cyclable ou celle destinée aux piétons pourra subsister. 



   Enfin, si par suite d'un choc vraiment trop violent un ou plusieurs éléments tournants venaient à se briser, ce qui est peu probable vu leur solidi- té, la réparation serait simple et très rapide, car il suffirait de remplacer le ou les pivots. 



   Pour réduire le prix de construction, le système peut se faire en fer et les éléments tournants en béton vibré; seulement, pour éviter la rouille, les frais d'entretien servaient plus importants.

   Various types of safety barriers are known intended to prevent accidents due in particular to the skidding of motor vehicles, from wooden barriers to metal barriers and to recent concrete barriers.



   The present invention relates to a barrier of this type, which has in particular over concrete barriers the advantage of very rapid placement and therefore allows a great saving in labor. This new barrier also has the impressive advantage of not damaging the roofs that come up against it.



   The safety barrier according to the present invention is essentially characterized in that it consists of a series of impact elements, such as rollers, mounted so as to be able to rotate freely around pivots vertically surmounting a strip of. metal preferably adapted to the profile of the ground to which it is fixed, so that said impact elements, made of relatively hardened material, have sufficient resistance to impacts, while braking by turning the tangential contact of the wheels of the vehicle deviated from its road,
By using suitable materials for the impact elements, their pivots and the backing strip, such a barrier will exhibit sufficient resistance not only to impact, but to weathering.



   The drawing appended to this specification shows, solely by way of example, one embodiment of a safety barrier in accordance with the invention.



  In this drawing: Figure 1 is a perspective view of a curved portion of a barrier, not attached to the solo
Figure 2 is an axial section through a shock roller, the barrier being attached to the solo
As shown in the drawing, the new barrier essentially comprises a series of varying lengths depending on the terrain of impact elements consisting of rollers 1 freely mounted around pivots 2 vertically surmounting a metal strip 3, it -even supported on the ground by piles or posts 4 driven into the latter, so that the band 3 adapts to the profile of the road
The shock rollers 1 are made of a relatively hard material so as to be able to withstand shocks and weathering, for example of rubber or of an appropriate syhthétique material.

   They will have for example as dimensions a diameter of 20 cm for a height of 22.5 cm; this height is calculated so as not to reach the bodywork, which could damage it. The rollers will be arranged leaving between them an interval of 2 centimeters, for example, so as to constitute a continuous surface. The pivots 2, of diameter slightly less than that of the holes drilled axially in the rollers 1, constitute threaded rods, which cross vertically strip 3; they hold the rollers between two washers 5, the upper washer being tightened by a nut 6, while the lower washer bears on the strip 3; 1 a nut 7 secures the pivot 2 to its base.

   These pivots and washers are made, for example, in brass or stainless steel.



   The strip 3 consists of a flat, preferably of stainless steel, the dimensions of which, for the shock rollers defined above, will be of the order of 20 cm wide by 5 cm thick, without this should be c considered as a limit one way or the other. The band 3 is fixed by all appropriate means: bolts, rivet, etcµ, on piles 4 driven into the ground S (Figo2), so as to ensure the band 3 nn resistant anchoring. These piles will preferably be concrete, but possibly they could be metal.

   It is easily understood that, thanks to the faculty of the rollers 1 of turning freely on their pivots 2, the wheels of vehicles which, during a skid for example, suddenly meet them, not only will be pushed back, but will be pushed back. tangentially braked in their advancement and brought back onto the road.



   It will also be noted that, due to the very small dimensions of the rollers 1, the cycle path or that intended for pedestrians may remain.



   Finally, if following a really too violent shock one or more rotating elements were to break, which is unlikely given their solidity, the repair would be simple and very quick, because it would suffice to replace the pivot (s). .



   To reduce the cost of construction, the system can be made of iron and the rotating elements of vibrated concrete; only, to avoid rust, the maintenance costs were more important.
