Abstract

A plate (1) of semi-rigid material provided on one of its faces with a reflecting material is equipped with two dorsal ribs (3) each comprising an axial recess forming a blind housing for a pin (9) made of rigid material. A metal base (5) consists of a supporting plate (8) provided with anchoring points (7) and an internally threaded drilled hole (6). The pin (9) is fully inserted in the drilled hole (6) of the base (5) on the one hand, and, on the other hand, in the recess of the rib (3). In the event of a violent impact, the pins break but the sharp breaking sections are protected by the body of the marker and this reduces the risk of injuries to road accident victims. <IMAGE>

Description

La présente invention concerne les balises routières et notamment les balises directionnenes délimitant des ilots ou des voies de circulation. De telles ba- lisessont constituées habituellement par des plaques en matériau semi-rigide munies sur au moins une de ses faces d'un matériau réfléchissant.The present invention relates to road beacons and in particular directional beacons defining islands or traffic lanes. Such marks are usually constituted by plates of semi-rigid material provided on at least one of its faces with a reflective material.

Des balises en béton ou en plastique rigide, connues par exemple du brevet français 2190979 ou du brevet américain 2121961, directem-nt ancrées au sol au moyen d'un organe rigide d'ancrage, sont destinées à être brisées en cas de choc violent. Elles présentent l'inconvénient soit d'être trop rigides et de constituer de ce fait un danger pour les motocyclistes, soit d'être trop facilement brisées par un choc même faible avec un véhicule. En cas de rupture, la balise doit être entièrement remplacée et le scellement au sol doit -etre refait.Concrete or rigid plastic beacons, known for example from French patent 2190979 or American patent 2121961, directly anchored to the ground by means of a rigid anchoring member, are intended to be broken in the event of violent impact. They have the disadvantage either of being too rigid and of thereby constituting a danger for motorcyclists, or of being too easily broken by an impact, even a slight one, with a vehicle. In the event of a break, the beacon must be completely replaced and the ground seal must be redone.

Pour les balises fléchissantes sous l'effet du choc, on connait, par exemple celle faisant objet du brevet français 1283975 constituée d'une plaque portée par une hampe retenue directement dans un scellement bétonné au moyen d'un fer rond traversant une ouverture ménagée au pied de la hampe. La plaque et la hampe étant en caoutchouc, la balise s'efface sous l'effet du choc, mais en cas d'une rupture il faut remplacer la balise et le scellement.For the bending beacons under the effect of the shock, we know, for example that forming the subject of French patent 1283975 consisting of a plate carried by a shaft retained directly in a concrete cementation by means of a round iron passing through an opening formed in the foot of the pole. The plate and the pole being made of rubber, the beacon disappears under the effect of the shock, but in the event of a rupture it is necessary to replace the beacon and the sealing.

Par ailleurs, on connait des balises ou des poteaux fléchissants comportant une plaque de signalisation retenue au moyen d'un organe d'ancrage par l'intermédiaire d'une pièce résiliente, soit un ressort selon le brevet allemand 1459817, soit un cylindre en caoutchouc selon le brevet français 1482473. De tels dispositifs ne peuvent tolérer des chocs très violents et le remplacement d'un système à ressort est, en cas de réutilisation d'une balise endommagée du fait d'un choc une opération délicate.Furthermore, beacons or bending posts are known comprising a signaling plate retained by means of an anchoring member by means of a resilient part, either a spring according to German patent 1459817, or a rubber cylinder. according to French patent 1482473. Such devices cannot tolerate very violent shocks and the replacement of a spring system is, in the event of re-use of a beacon damaged due to an impact, a delicate operation.

La présente invention a pour objet une balise permettant d'éviter les inconvénients cités et notam-ent en ce qui concerne la rapidité et la fragilité aux chocs et dont la pose rapide ne nécessite aucun scellement au sol, tandis que la partie endommagée peut être remplacée au moindre coût.The subject of the present invention is a beacon making it possible to avoid the aforementioned drawbacks and in particular as regards speed and fragility to impact and the rapid installation of which requires no sealing on the ground, while the damaged part can be replaced. at the lowest cost.

La balise selon l'invention est caractérisée en ce que sa plaque en matériau semi-rigide, tel que les caoutchoucs SBR et EPDM et autres produits élastomères, est traversée par au moins un évidement longitudinal et en ce que les moyens de fixation au sol sont constitués par une broche, tube ou goujon en matériau rigide et une embase métallique destinée à être enfoncée entièrement dans le sol et munie de moyens de retenue de la broche et dun perçage ou évidement longitudinal, la broche étant entièrement engagée d'une part dans le perçage de l'embase et d'autre part dans l'évidement de la plaque.The tag according to the invention is characterized in that its plate made of semi-rigid material, such as SBR and EPDM rubbers and other elastomeric products, is crossed by at least one longitudinal recess and in that the means for fixing to the ground are constituted by a spindle, tube or stud made of rigid material and a metal base intended to be driven entirely into the ground and provided with means for retaining the spindle and with a drilling or longitudinal recess, the spindle being fully engaged on the one hand in the drilling the base and on the other hand in the recess of the plate.

Il était connu du brevet français 2423586 de munir un panneau de signalisation des deux tubes ou tiges de raidissement noyés dans les bordures du panneau, lesdits tubes dépassant la plaque et formant les support du panneau, au moyen desquels celui-ci est fixé à un pied. Les points de cassure se produisant en cas de choc entre le panneau et le pied sur les parties libres et dégagées des tubes dépassant le panneau, les sections de rupture tranchantes sont susceptibles d'occasionner de graves blessures aux accidentés. Dans le dispositif selon l'invention, en cas de choc violent, les broches en plastique rigide se rompent, mais les sections de cassure sont entièrement protégées par le corps de la balise. En outre, la cassure de la broche se produit le plus souvent à l'endroit de la jonction de l'embase et de la plaque, au ras de l'embase, ce qui réduit le risque de blessures.It was known from French patent 2423586 to provide a sign for the two stiffening tubes or rods embedded in the edges of the panel, said tubes protruding beyond the plate and forming the panel supports, by means of which the latter is fixed to a foot . Since break points occur in the event of an impact between the panel and the foot on the free and cleared parts of the tubes protruding from the panel, the sharp breaking sections are likely to cause serious injury to accident victims. In the device according to the invention, in the event of a violent impact, the rigid plastic pins break, but the break sections are entirely protected by the body of the tag. In addition, spindle breakage most often occurs at the junction of the base and the plate, flush with the base, which reduces the risk of injury.

Les broches sont réalisées en un matériau plastique rigide, tel que le polypropylène, ou en métal malléable, tel que l'aluminium.The pins are made of a rigid plastic material, such as polypropylene, or of malleable metal, such as aluminum.

Elles peuvent présenter la forme d'un tube, d'un jonc ou d'un goujon, dont au moins une extrémité est munie d'un filetage mâle.They may have the shape of a tube, a rod or a stud, at least one end of which is provided with a male thread.

L'embase métallique peut prendre la forme d'une plaque d'appui munie de pointes d'ancrage verticales, un perçage muni d'un filetage femelle étant pratiqué dans la plaque d'appui. Elle peut aussi se présenter sous forme d'un tube métallique pourvu de moyens de retenue de la broche. Ces moyens de retenue peuvent consister soit en une tige d'arrêt traversant la partie inférieure du tube, soit d'un filetage femelle à la partie supérieure du tube. Le mode de fixation de la broche à l'embase est soit par vissage dans le perçage taraudé de la plaque d'appui ou du tube métallique, soit il peut consister à faire reposer la broche par sa base sur la tige d'arrêt traversant le tube métallique.The metal base can take the form of a support plate provided with vertical anchoring points, a bore provided with a female thread being formed in the support plate. It can also be in the form of a metal tube provided with means for retaining the spindle. These retaining means may consist either of a stop rod passing through the lower part of the tube, or of a female thread at the upper part of the tube. The method of fixing the spindle to the base is either by screwing into the tapped hole in the support plate or the metal tube, or it can consist of resting the spindle by its base on the stop rod passing through the metal tube.

De préférence, la balise dont le corps est en forme de plaque renforcée par des nervures ou des bordures est munie d'au moins une nervure dorsale comportant un évidement axial, laquelle nervure peut être prolongée par des fines nervures.Preferably, the beacon whose body is in the form of a plate reinforced by ribs or edges is provided with at least one dorsal rib comprising an axial recess, which rib can be extended by fine ribs.

Ledit évidement ou perçage peut former un logement borgne, auquel cas la broche est encastrée de force dans l'évidement.Said recess or hole can form a blind housing, in which case the spindle is forced into the recess.

Selon une variante, les nervures dorsales comportant un perçage axial ne s'étendent que sur la partie inférieure de la plaque et dans ce cas, le perçage débouche à l'extrémité supérieure de la nervure, la partie émergeante de la broche engagée dans ledit évidement étant filetée pour être bloquée au moyen d'un écrou.According to a variant, the dorsal ribs comprising an axial bore only extend over the lower part of the plate and in this case, the bore opens at the upper end of the rib, the emerging part of the spindle engaged in said recess being threaded to be locked with a nut.

De préférence, chaque balise comporte deux fixations réparties le long de son bord inférieur, afin d'éviter notamment que la balise puisse tourner autour de son axe.Preferably, each tag has two fasteners distributed along its lower edge, in order to avoid in particular that the tag can rotate around its axis.

L'embase peut comporter soit une plaque d'appui munie de pointes d'ancrage et pourvue de deux perçages espacés pour la fixation de deux broches, soit deux tubes métalliques parallèles dont l'espacement est maintenu par fixation d'une plaquette métallique.The base may include either a support plate provided with anchoring points and provided with two spaced holes for fixing two pins, or two parallel metal tubes, the spacing of which is maintained by fixing a metal plate.

Le procédé d'ancrage de la balise selon l'invention consiste à, dans un ordre quelconque, mettre en place la ou les embases par enfoncement de leurs pointes dans le sol, solidariser avec chaque embase la ou les broches verticales pour lesquelles des moyens de fixation ou de retenue sont prévus dans ladite embase, engager les broches dans les évidements de la plaque. Selon les appareils dont on dispose pour la mise en place des balises, on peut enfoncer les embases en utilisant éventuellement un calibre, mettre en place les broches par exemple en les vissant dans un taraudage de l'embase, puis mettre en place la balise. Il est également possible de fixer au préalable sur les embases soit en usine, soit sur le chantier, et enfin il est possible, notamment en utilisant une pièce de transmission d'effort emboîtant la balise munie de ses broches et de leurs embases, d'enfoncer en une seule opération, l'ensemble assemblé et mis en forme au préalable.The method for anchoring the beacon according to the invention consists in, in any order, setting up the base or bases by driving their points into the ground, securing with each base the vertical pin or pins for which means of fixing or retaining are provided in said base, engage the pins in the recesses of the plate. Depending on the devices available for setting up the beacons, the bases can be inserted using a gauge, if necessary, put the pins in place for example by screwing them into a thread on the base, then put the beacon in place. It is also possible to fix beforehand on the bases either in the factory or on the site, and finally it is possible, in particular by using a force transmission part fitting the beacon provided with its pins and their bases, press in a single operation, the assembly assembled and shaped beforehand.

En cas de choc, la balise en caoutchouc se déforme élastiquement et ce n'est qu'en cas de choc violent que les broches en plastique rigide sont susceptibles de se rompre, les sections de rupture éventuellement tranchantes restent protégées par le corps de la balise. Les broches brisées peuvent être extraites et remplacées, ou elles peuvent être réassemblées par collage éventuellement avec renfort axial dans le cas de broches engagées à force.In the event of impact, the rubber beacon deforms elastically and it is only in the event of a violent impact that the rigid plastic pins are liable to break, the possibly sharp breaking sections remain protected by the body of the beacon . Broken pins can be removed and replaced, or they can be reassembled by gluing, optionally with axial reinforcement in the case of pins engaged by force.

La surface en un matériau réfléchissant peut être réalisée de toute manière connue.The surface of a reflective material can be produced in any known manner.

D'une manière générale la balise routière comporte un panneau 1 constitué par une plaque en caoutchouc rigide pouvant avoir toute forme voulue selon la forme définitive de la balise. Sur cette plaque est ou sont fixées de toute manière connue, par exemple par rivetage, collage ou encastrement des bords, une ou des surfaces réfléchissantes 2.In general, the road beacon comprises a panel 1 constituted by a rigid rubber plate which can have any desired shape depending on the final shape of the beacon. On this plate is or are fixed in any known manner, for example by riveting, gluing or embedding of the edges, one or more reflecting surfaces 2.

La rigidité de la plaque peut être accrue par des nervures dorsales. Dans divers modes de réalisation représentés, ces nervures dorsales 3 servent également à la fixation en place des balises. Poùrce faire(et dans les modes de réalisation des figures 1 à 4 et 8), chaque nervure comporte un évidement axial 4 formant un logement borgne. Les embases 5, par exemple en acier et tôle galvanisé , comportent un perçage axial 6 fileté et un certain nombre de dents verticales 7 (quatre dans le mode représenté) solidaires de la plaque d'appui 8. L'embase peut être mise en place dans le sol du bas côté par enfoncement à la masse ou à l'aide d'un vérin porté par le camion de pose, les dents pouvant, malgré leur rigidité, se déformer, ce qui améliore l'ancrage.The rigidity of the plate can be increased by dorsal ribs. In various embodiments shown, these dorsal ribs 3 are also used for fixing tags in place. To do this (and in the embodiments of Figures 1 to 4 and 8), each rib has an axial recess 4 forming a blind housing. The bases 5, for example made of steel and galvanized sheet, have an axial bore 6 threaded and a number of vertical teeth 7 (four in the mode shown) integral with the support plate 8. The base can be put in place in the ground on the lower side by driving in ground or using a jack carried by the laying truck, the teeth being able, despite their rigidity, to deform, which improves anchoring.

Une broche en matière plastique rigide 9 ou en métal malléable est vissée dans le perçage taraudé 6 de l'embase. Cette broche présente sur sa longueur en saillie des collets tronconiques 10 de manière qu'après mise en place dans l'évidement axial de la nervure en caoutchouc dur, l'arrachage en soit pratiquement impossible ou à tout le moins difficile.A pin of rigid plastic 9 or of malleable metal is screwed into the threaded bore 6 of the base. This spindle has frustoconical collars 10 along its protruding length so that, after being placed in the axial recess of the hard rubber rib, tearing is practically impossible or at the very least difficult.

Du fait de la présence d'au moins deux broches 9 sur une même balise, le plan de la balise est fixé et ne peut être modifié à la suite d'un accident ou autre.Due to the presence of at least two pins 9 on the same beacon, the plane of the beacon is fixed and cannot be modified following an accident or the like.

Dans le cas des figures 3 et 4 qui correspondent à une balise de tête d'ilot, la plaque 1 comporte trois nervures 3 et la position des embases définit également la forme après pose de la balise.In the case of FIGS. 3 and 4 which correspond to an island head tag, the plate 1 has three ribs 3 and the position of the bases also defines the shape after fitting the tag.

Lors de la pose, les embases 6 à 8 peuvent tout d'abord être enfoncées en place, après quoi on visse les broches 9 et met en place la plaque 1 formant la balise proprement dite. Il est toutefois possible que les embases soient mal placées ou décalées pendant leur enfoncement. En conséquence et selon un autre procédé, on assemble la balise, ses broches et ses embases et la balise est engagée dans une tête de vérin comportant une chambre à sa forme définitive et les embases sont enfoncées simultanément au vérin. Il serait également possible, notamment lorsque le sol dans lequel doit être effectué l'ancrage est trop dur, d'ancrer les embases de la manière classique, les broches pouvant être réalisées en une seule pièce avec embase. Dans le mode de réalisation des figures 5 à 7, les nervures dorsales 3' comportant un évidement axial 41 sont limitées à la partie inférieure de la plaque et elles se prolongent au-délà de la section 11 jusqu'au bord supérieur de la plaque par deux. nervures fines en forme des ailes latérales parallèles 12 de hauteur décroissante. Une nervure de renfort 13, est prévue à la partie supérieure et le long du bord de la plaque. Les broches 9' en plastique rigide, pleines ou tubulaires, sont vissées dans les taraudages de l'embase 5' commune pour les deux broches d'une .même balise. Les extrémités supérieures des broches 9' font saillie au-délà de la section 11 entre les deux ailes 12 et sur l'extrémité filetée en saillie est vissé un écrou 14 ou engagé à force un dispositif de blocage analogue.During installation, the bases 6 to 8 can first of all be pushed into place, after which the pins 9 are screwed and the plate 1 sets up the tag itself. However, it is possible that the bases are incorrectly positioned or offset during their insertion. Consequently and according to another method, the beacon, its pins and its bases are assembled and the beacon is engaged in a jack head comprising a chamber at its final shape and the bases are pressed simultaneously to the jack. It would also be possible, in particular when the ground in which the anchoring is to be carried out is too hard, to anchor the bases in the conventional manner, the pins being able to be produced in one piece with base. In the embodiment of FIGS. 5 to 7, the dorsal ribs 3 ′ comprising an axial recess 4 1 are limited to the lower part of the plate and they extend beyond section 11 to the upper edge of the plate by two. fine ribs in the form of parallel lateral wings 12 of decreasing height. A reinforcing rib 13 is provided at the upper part and along the edge of the plate. The pins 9 'of rigid plastic, full or tubular, are screwed into the threads of the base 5' common for the two pins of the same tag. The upper ends of the pins 9 'protrude beyond the section 11 between the two wings 12 and on the projecting threaded end is screwed a nut 14 or forcibly engaged a similar locking device.

La variante selon la figure 8 représente une balise 1 munie de nervures dorsales 3 comportant des évidements formant de logements borgnes. Deux formes de réalisation de la fixation de la plaque sur l'embase sont représentées à la figure 8.The variant according to FIG. 8 represents a beacon 1 provided with dorsal ribs 3 comprising recesses forming blind housings. Two embodiments of the fixing of the plate to the base are shown in FIG. 8.

Dans sa première forme figurant du côté gauche du dessin, l'embase est con- stituéepar un tube 15 en acier galvanisé se terminant en pointe d'ancrage et muni à sa partie supérieure d'une rondelle d'appui 16 et traversé à sa partie inférieure d'une tige d'arrêt 17. Une broche 18 est un tube lisse en polypropylène reposant par sa base sur la tige 17 et logé dans l'évidement de la nervure.In its first form appearing on the left side of the drawing, the base is constituted by a tube 15 made of galvanized steel ending in an anchor point and provided at its upper part with a support washer 16 and traversed at its part lower of a stop rod 17. A pin 18 is a smooth polypropylene tube resting at its base on the rod 17 and housed in the recess of the rib.

Dans sa deuxième forme de réalisation figurant du côté droit du dessin, l'embase est constituée également par un tube en acier galvanisé dont l'extrémité inférieure présente une pointe et dont l'extrémité supérieure possède un filetage femelle19, par exemple sous forme d'une bague taraudée. La broche 20 se présente sous forme d'un goujon dont les deux extrémités possèdent une partie filetée 21 munie d'un trou borgne central non représenté.In its second embodiment appearing on the right side of the drawing, the base also consists of a galvanized steel tube whose lower end has a point and whose upper end has a female thread19, for example in the form of a threaded ring. The pin 20 is in the form of a stud, the two ends of which have a threaded part 21 provided with a central blind hole not shown.

Les procédés de montage et de fixation des balises présentant soit un mode de fixation soit l'autre sont similaires à ceux déjà décrits.The methods of mounting and fixing the beacons having either one fixing method or the other are similar to those already described.

Ces deux formes de réalisation présentent l'avantage de salifier l'opé- ratio d'extraction de la partie de la broche restée après cassure dans les tubes d'ancrage. Dans le cas du goujon 20 vissé, le trou borgne dont il est muni permet aisément une telle extraction. Un même goujon , lorsqu'il est muni de filetages à ses deux extrémités, peut être réutilisé après cassure, le secondfiletage prenant la place du premier.These two embodiments have the advantage of salifying the extraction operation of the part of the spindle remaining after breakage in the anchoring tubes. In the case of the screwed stud 20, the blind hole with which it is provided easily allows such extraction. The same stud, when fitted with threads at both ends, can be reused after breaking, the second thread taking the place of the first.

Les modes de réalisation décrits ci-dessus à titre d'exemple sont susceptibles de recevoir de nombreuses modifications sans sortir du cadre de la présente invention.The embodiments described above by way of example are capable of receiving numerous modifications without departing from the scope of the present invention.
