Abstract

Each road marker is embedded in a correspondingly shaped hole in the road surface. The upper part of the marker body (1) projects as a spherical cap (6) and is provided with a recess (7) which receives an interchangeable cartridge (8) carrying reflective elements. The cartridge pref. has a hollow base (12) into which a projection (13) in the recess locates. The reflective elements are pref. glued to opposite ends of each cartridge. The cartridge is pref. secured to the marker body by a screw.

Description

La présente invention est relative à un plot de balisage routier comportant des éléments rétroréfléchissants permettant d'indiquer au conducteur d'un véhicule la délimitation d'une chaussée, son axe médian, etc. The present invention relates to a road marking block comprising retroreflective elements making it possible to indicate to the driver of a vehicle the delimitation of a roadway, its median axis, etc.

On connaft des plots de balisage routier comportant un corps généralement en céramique posé et fixé sur le revetement de la chaus
see au moyen de colle, sur le corps est rapporté et maintenu par colle un ou plusieurs éléments rétroréflèchissants disposé/s dans un emplacement prévu à cet effet pour le ou les recevoir. Etant donné les efforts auxquels lesdits plots sont soumis lors du passage des véhicules, ces derniers s' arrachent à plus ou moins longue échéance, parfois ils éclatent, d'autre part les plaquettes rétroréfléchîssantes sont soumises elles aussi à arrachemenssc, leur remplacement sur route est pratiquement impossible.
There are road markers with a generally ceramic body placed and fixed on the lining of the shoe
see by means of glue, on the body is attached and held by glue one or more retroreflective elements arranged / s in a location provided for this purpose for or receive them. Given the efforts to which said studs are subjected during the passage of the vehicles, the latter tear off at more or less long term, sometimes they burst, on the other hand the retro-reflective plates are also subject to tear-off, their replacement on the road is practically impossible.

L'invention a pour but de palier aux inconvénients précédemment exposés. The invention aims to overcome the drawbacks previously exposed.

L'invention a en conséquence pour objet un plot de balisage routier comportant un corps cylindrique ou tout autre forme en matière inaltérable, stemboftant dans un évidement de section similaire aménagé à mGme le revêtement dans lequel il est maintenu par colle de sorte à réaliser un encastrement, sur ledit plot est aménagé un logement pour recevoir une cartouche interchangeable dotée d'éléments rétrofléchissants. The subject of the invention is therefore a road marking block comprising a cylindrical body or any other form of unalterable material, stemboftant in a recess of similar section arranged in the same way as the covering in which it is held by glue so as to create an embedding. , on said pad is arranged a housing for receiving an interchangeable cartridge provided with retroreflective elements.

D'autres caractéristiques et avantages de l'invention ressortiront plus clairement de la description qui va suivre faite en regard des dessins joints donnés à titre d'exemple non limitatif où
- la figure 1 est une vue en coupe du plot dans l'axe longitudinal de la cartouche interchangeable dotée des éléments rëtrofléchissants,
- la figure 2, une vue en coupe suivant l'axe transversal de la cartouche interchangeable,
- la figure 3, une vue de dessus du plot.
Other characteristics and advantages of the invention will emerge more clearly from the description which follows, given with regard to the accompanying drawings given by way of non-limiting example where
FIG. 1 is a sectional view of the stud in the longitudinal axis of the interchangeable cartridge provided with retroreflective elements,
FIG. 2, a sectional view along the transverse axis of the interchangeable cartridge,
- Figure 3, a top view of the stud.

Comme représenté figures 1, 2 et 3 > le plot objet de l'invention, comporte un corps I en matière inaltérable tel que métal par exemple, de section circulaire, la partie 2 destinée à s'embouer dans un évidement 3 lui-même circulaire aménagé à même le revêtement 4 de la chaussée est évidée ou non en sa partie centrale 5, la partie 6 constituant le chapeau, saillante du sol, présente une forme arrondie du type calotte sphérique pourvue d'un évidement 7 en sa partie centrale destiné à recevoir une cartouche interchangeable 8 dotée d'éléments rétroréfléchissants 9 collés dans des rainurés 10 aménagées à cet effet en contre parement sur la partie centrale 20 en matiere identique ou différente du corps 1, en parement la matière restante constitue une lèvre 11 protégeant les éléments rétroréfléchissants des efforts d'arrachement.La cartouche interchangeable 8 est pourvue d'un évidement central 12 en forme de quadrilatère par exemple s'enfourchant sur une protubérance centrale 13 de section correspondante afin d'empécher tout glissement et de ce fait son immobilisation, le maintien de la cartouche interchangeable 8 est assurée par une vis 14 d'assemblage sur le corps 1. L'ancrage du corps 1 dans l'évidement 3 du revêtement 4 est assuré par colle, afin de renforcer cet ancrage, un ou plusieurs bourrelets 15 peuvent etre aménagés à même la périphérie du corps 1, comme pour raidir le chapeau 6, des raidisseurs 16 peuvent entre prévus. Sans sortir du cadre de l'invention, la partie centrale 5 évidée peut être obturée par une plaque rapportée 17 et ce afin de réduire la quantité de colle servant à réaliser l'encastrement, dans le même esprit l'évidement central 5 peut entre comblé par une matière de remplissage différente du corps 1 ou similaire. As shown in FIGS. 1, 2 and 3> the stud which is the subject of the invention, comprises a body I of unalterable material such as metal for example, of circular section, the part 2 intended to be embedded in a recess 3 which is itself circular laid out on the same surface 4 of the floor is hollowed out or not in its central part 5, the part 6 constituting the cap, projecting from the ground, has a rounded shape of the spherical cap type provided with a recess 7 in its central part intended to receive an interchangeable cartridge 8 provided with retroreflective elements 9 glued in grooves 10 arranged for this purpose in counter facing on the central part 20 of identical or different material from the body 1, in facing the remaining material constitutes a lip 11 protecting the retroreflective elements The interchangeable cartridge 8 is provided with a central recess 12 in the form of a quadrilateral for example straddling a central protuberance 13 of section corresponding in order to prevent any slipping and thereby its immobilization, the interchangeable cartridge 8 is maintained by a screw 14 for assembly on the body 1. The anchoring of the body 1 in the recess 3 of the covering 4 is provided by glue, in order to reinforce this anchoring, one or more beads 15 can be fitted to the very periphery of the body 1, as if to stiffen the cap 6, stiffeners 16 can be provided. Without departing from the scope of the invention, the central part 5 which is hollowed out can be closed off by an attached plate 17 and this in order to reduce the quantity of glue used for embedding, in the same spirit the central recess 5 can be filled in by a filling material different from the body 1 or similar.

De manière à élargir le champ de réflexion lumineuse, les côtés 18 de l'évidement 7 recevant la cartouche interchangeable 8 se prolongent en 19 suivant un angle ouvert, ledit angle permettant en outre l'autonettoyage des éléments rétrofléchissants par temps de pluie grâce au phénomène d'aquaplaning des pneumatiques. In order to widen the light reflection field, the sides 18 of the recess 7 receiving the interchangeable cartridge 8 are extended at 19 at an open angle, said angle also allowing self-cleaning of the retroreflective elements in rainy weather thanks to the phenomenon aquaplaning of tires.
