Description

La présente invention concerne le domaine de la signalisation sur des voies de communication, ou tout lieu destiné à accueillir des véhicules. Plus particulièrement l'invention concerne un dispositif de balisage rabattable dans le sol que l'on redresse pour indiquer différentes informations au conducteur d'un véhicule, comme défini dans le préamble de la revendication 1. Un tel dispositif est connu du document US-A-4 713 910 .The present invention relates to the field of signaling on communication routes, or any place intended to accommodate vehicles. More particularly, the invention relates to a ground folding marker device which is adjusted to indicate different information to the driver of a vehicle, as defined in the preamble of claim 1. Such a device is known from the document. US-A-4,713,910 .

Sur certaines routes ou voies ferrées, certaines informations récurrentes n'ont besoin d'être indiquées qu'à un moment précis. C'est par exemple le cas pour des embouteillages, des vents latéraux, des accidents. Cela peut aussi être utilisé pour indiquer un sens de circulation de façon momentané, comme en cas de travaux.On certain roads or railways, some recurring information need only be indicated at a specific time. This is for example the case for traffic jams, side winds, accidents. This can also be used to indicate a direction of movement momentarily, as in the case of work.

Certains systèmes utilisent des bornes rétractables dans le sol. Ainsi, le brevet US 4713910 décrit une balise comportant sur sa longueur une crémaillère qui coopère avec un engrenage situé à l'intérieur du sol, permettant à un moteur de descendre et de monter la balise. Le problème de ces balises rétractables est qu'elles nécessitent un certain temps pour être sorties et rentrées dans le sol. Aussi le brevet US 4713910 prévoit également des balises rabattables. Celles-ci sont articulées autour d'un axe permettant le rabattement de la balise à l'intérieur d'un évidement prévu dans le sol. La balise est creuse afin d'accueillir le mécanisme permettant son redressement. La balise doit donc être renforcée pour protéger le mécanisme de tout choc. Ces balises sont utilisées pour interdire l'accès d'une zone à un véhicule et non comme moyen de signalisation sur des voies de circulation. Elles constituent donc des barrières physiques et ne peuvent être que rabaissées dans un sens sur commande de l'utilisateur. Ainsi lorsqu'elles subissent un choc avec un véhicule, celles-ci cassent ou endommagent le véhicule.Some systems use retractable terminals in the ground. Thus, the patent US 4713910 describes a beacon having along its length a rack which cooperates with a gear located inside the ground, allowing a motor to go down and mount the beacon. The problem with these retractable beacons is that they require a certain amount of time to get out and into the ground. Also the patent US 4713910 also provides foldable tags. These are articulated around an axis allowing the folding of the beacon inside a recess provided in the ground. The tag is hollow to accommodate the mechanism for its recovery. The beacon must be reinforced to protect the mechanism from any shock. These beacons are used to prohibit the access of an area to a vehicle and not as a means of signaling on taxiways. They therefore constitute physical barriers and can only be lowered in a direction to the user's command. Thus when they suffer a shock with a vehicle, they break or damage the vehicle.

Le brevet US 4552089 concerne des balises rabattables amovibles destinées à la signalisation. Il s'agit d'un dispositif permettant d'installer plusieurs balises en même temps. Celles-ci sont également articulées autour d'un axe, leur permettant de se rabattre dans un réceptacle.The patent US 4552089 relates to removable folding tags for signaling. This is a device to install multiple tags at the same time. These are also articulated around an axis, allowing them to fall back into a receptacle.

L'ensemble du dispositif est amovible. Lorsque le dispositif est installé sur la chaussée, un ressort permet le redressement de la balise, de sorte que celle-ci est verticale. L'enroulement permet d'exercer une contrainte sur la balise et de rabattre celle-ci à l'intérieur du réceptacle. Ainsi, une fois en position au niveau de la voie de circulation, la balise n'est pas actionnable en redressement et en rabattement, mais reste en position fixe. De plus, une contrainte subie dans le sens contraire au rabattement dans le réceptacle entraîne un endommagement de la balise puisqu'aucune rotation dans ce sens n'est prévue. Ceci peut être gênant pour démarquer deux voies de circulation à double sens.The entire device is removable. When the device is installed on the road, a spring allows the recovery of the beacon, so that it is vertical. The winding makes it possible to exert a constraint on the beacon and to fold it down inside the receptacle. Thus, once in position at the taxiway, the beacon is not operable in recovery and drawdown, but remains in a fixed position. In addition, a constraint experienced in the direction opposite to folding in the receptacle causes damage to the tag since no rotation in this direction is provided. This can be inconvenient to distinguish two two-way traffic lanes.

Le document FR2124197 concerne un dispositif permettant de protéger l'accès d'un parking. Le dispositif comprend un arceau pouvant être levé d'une position horizontale (permettant l'accès au parking) vers une position verticale (interdisant l'accès au parking) en appuyant avec le pied sur une pédale faisant partie d'un levier permettant de déplacer l'arceau dans une position verticale. Lorsque l'arceau est en position verticale, le mouvement dudit arceau est automatiquement biloqué avec un verrouillage. Ce verrouillage peut être débloque grâce à l'utilisation d'un électro-aimant faisant basculeur le verrouillage et permettant ainsi de basculer ledit verrouillage vers une position pour lisérer le mouvement de l'arceau.The document FR2124197 relates to a device for protecting access to a parking lot. The device comprises a hoop that can be lifted from a horizontal position (allowing access to the parking) to a vertical position (prohibiting access to the parking) by pressing with the foot on a pedal forming part of a lever for moving the hoop in a vertical position. When the hoop is in the vertical position, the movement of said hoop is automatically bilocated with a lock. This locking can be unlocked through the use of an electromagnet rocking the lock and thus toggling said lock to a position to read the movement of the arch.

Le document FR2609069 concerne un dispositif permettant de renforcer la signalisation de passagers piétons en utilisant un élément pouvant se déplacer d'un logement, dans lequel ledit élément est reçu dans sa position verticale, vers une deuxième position vers laquelle l'extrémité du dispositif est visible au-dessus de son logement. Le mouvement du dispositif de signalisation est obtenu grâce à l'utilisation d'air comprimé. Le dispositif selon FR2609069 peut être équipé d'une articulation, cette articulation se trouvant au niveau du sol pour permettre au dispositif de basculer en cas de passage d'un véhicule.The document FR2609069 relates to a device for reinforcing pedestrian passenger signaling by using a moveable member of a housing, wherein said member is received in its upright position, to a second position towards which the end of the device is visible above of his dwelling. The movement of the signaling device is achieved through the use of compressed air. The device according to FR2609069 can be equipped with a hinge, the hinge being at ground level to allow the device to tilt in case of passage of a vehicle.

Le but de la présente invention est de permettre l'utilisation de balises rabattables dans le sol, capables en cas de choc avec un véhicule de se coucher pour rester en état de marche sans endommager le véhicule que le choc ait lieu dans un sens de la circulation ou dans l'autre, et pouvant ainsi être positionnées au milieu d'une voie de circulation. Ces balises doivent également pouvoir être érigées et rabattues sur commande sans que le dispositif ne quitte son emplacement.The object of the present invention is to allow the use of folding tags in the ground, able in case of shock with a vehicle to lie down to stay in working condition without damaging the vehicle that the shock takes place in a direction of the traffic or in the other, and can thus be positioned in the middle of a traffic lane. These tags must also be able to be erected and folded to order without the device leaving its location.

Plus précisément l'objet de la présente invention est un dispositif de balisage comme définit dans la revendication 1.More precisely, the subject of the present invention is a marking device as defined in claim 1.

Les buts, objets et caractéristiques de l'invention apparaîtront plus clairement à la lecture de la description qui suit faite en référence aux dessins dans lesquels :

  • la figure 1 représente l'ensemble du dispositif selon une réalisation préférentielle de la présente invention, et
  • la figure 2 représente un comportement du dispositif selon la présente invention selon un cas donné.
The objects, objects and features of the invention will appear more clearly on reading the following description given with reference to the drawings in which:
  • the figure 1 represents the entire device according to a preferred embodiment of the present invention, and
  • the figure 2 represents a behavior of the device according to the present invention according to a given case.

Le dispositif de balisage, tel que représenté en figure 1, est destiné à être inséré dans le sol 3. Il est composé d'un élément de balisage 2, qui comprend un moyen de signalisation 5, de sorte que lorsqu'il est redressé, l'élément de balisage ou balise est en position de signalisation et est visible de loin par les conducteurs. La balise 2 comprend un axe de rotation 7, autour duquel elle peut effectuer une rotation de 90 degrés de la position horizontale à la position verticale ou quasi-verticale. La position horizontale de la balise 2 est ci-après appelée la première position et la position verticale ou quasi-verticale est ci-après appelée la deuxième position de la balise 2. Ainsi, la balise peut se rabattre au niveau du sol, notamment en venant se loger dans le sol à l'intérieur d'un évidement prévu à cet effet, préférentiellement dans un boîtier 8 inséré dans le sol et aux dimensions de la balise. Le redressement en position horizontale et le rabattement en position verticale ou quasi-verticale de la balise 2, est assuré par un moyen d'actionnement. La balise peut donc être relevée ou rabattue sur commande grâce à ce moyen d'actionnement selon la situation à signaler. De même, en cas de choc dans le sens du rabattement, la balise 2 se rabattra dans le sol. Pour répondre à un choc dans l'autre sens, la balise comprend une articulation élastique 4 située au-dessus de l'axe de rotation 7. Ainsi, lorsqu'un tel choc a lieu, la balise va se tordre au niveau de cette articulation sous l'effet de la contrainte, la zone située au-dessous de l'axe de rotation 7 étant en appui contre le sol, et revenir dans la position verticale lorsque cette contrainte aura cessé. L'articulation élastique 4 permet donc à la balise de ployer jusqu'à 180 degrés par rapport à sa position de rabattement au niveau du sol. La figure 4 illustrant ce genre de contrainte représente un véhicule qui en passant sur la balise 2 va coucher celle-ci. Lors du passage du véhicule, la balise est couchée et en frottement sous celui-ci. Dés qu'il sera passé, la balise reviendra en position initiale, à savoir la position verticale ou quasi-verticale.The marking device, as represented in figure 1 , it is intended to be inserted in the ground 3. It is composed of a markup element 2, which comprises a signaling means 5, so that when it is straightened, the markup element or beacon is in the position of signaling and is visible from afar by drivers. The beacon 2 comprises an axis of rotation 7, around which it can rotate 90 degrees from the horizontal position to the vertical or quasi-vertical position. The horizontal position of the beacon 2 is hereinafter called the first position and the vertical or quasi-vertical position is hereinafter called the second position of the beacon 2. Thus, the beacon can fall back to the ground level, particularly in housed in the ground inside a recess provided for this purpose, preferably in a housing 8 inserted into the ground and the dimensions of the tag. The rectification in horizontal position and the folding in the vertical or near vertical position of the beacon 2, is provided by an actuating means. The beacon can be raised or folded on command by this means of actuation according to the situation to report. Similarly, in case of impact in the direction of folding, the tag 2 will fall back into the ground. To respond to a shock in the other direction, the beacon comprises an elastic articulation 4 located above the axis of rotation 7. Thus, when such a shock occurs, the beacon will twist at this joint under the effect of stress, the area below the axis of rotation 7 bearing against the ground, and return to the vertical position when this constraint has ceased. The elastic joint 4 allows the beacon to bend up to 180 degrees from its drawdown position at ground level. Figure 4 illustrating this kind of constraint represents a vehicle that passing on the beacon 2 will sleep it. When passing the vehicle, the tag is lying and rubbing under it. As soon as it is passed, the beacon will return to the initial position, namely the vertical or near-vertical position.

Préférentiellement l'articulation est constituée d'une pièce 4 en matière souple et élastique, tel que du polyuréthane, comprenant un rétrécissement 6 au niveau duquel se fait une torsion lorsque la balise 2 subit une contrainte opposée à son sens de rabattement au niveau du sol. L'élasticité du matériau permet à la balise 2 de revenir en position verticale ou quasi-verticale.Preferably, the joint consists of a piece 4 of flexible and elastic material, such as polyurethane, comprising a narrowing 6 at which is twisting when the tag 2 is subjected to a constraint opposite to its direction of drawdown at ground level . The elasticity of the material allows the beacon 2 to return to the vertical or near-vertical position.

Préférentiellement le moyen d'actionnement génère un mouvement de translation d'une crémaillère 42 couplée directement à un premier engrenage 44, le mouvement de translation est ainsi transformé en un mouvement de rotation. Sur la figure 1, le premier engrenage 44 est couplé à un second engrenage 46 fixé à la balise 2, de sorte que la rotation du premier engrenage dans un sens entraîne la rotation de la balise dans l'autre sens, et ainsi rabat ou redresse la balise. Il peut également être envisagé un seul engrenage qui est directement fixé à la balise 2 et couplé à la crémaillère 42. De même, le nombre d'engrenages peut être supérieur à deux. Tel que représenté en figure 1, le positionnement vertical de la crémaillère et le nombre pair d'engrenages implique que la descente de la crémaillère 42 entraîne la remontée de la balise 2.Preferably the actuating means generates a translation movement of a rack 42 coupled directly to a first gear 44, the translational movement is thus transformed into a rotational movement. On the figure 1 , the first gear 44 is coupled to a second gear 46 fixed to the beacon 2, so that the rotation of the first gear in one direction causes the beacon to rotate in the other direction, and thus flip or rectify the beacon. It can also be envisaged a single gear that is directly attached to the tag 2 and coupled to the rack 42. Similarly, the number of gears can be greater than two. As represented in figure 1 , the vertical positioning of the rack and the even number of gears implies that the descent of the rack 42 causes the raising of the beacon 2.

Le moyen d'actionnement peut comprendre un électro-aimant qui lorsqu'il est activé permet à l'élément de balisage ou balise 2 de passer de l'une à l'autre desdites première et deuxième positions. Dans le cas où le dispositif 1 comprend un couple crémaillère engrenage, tel que cela est représenté en figure 1, l'électro-aimant entraîne la translation de la crémaillère 42. Ce dernier comprend un étrier 12 destiné à être fixé dans le sol, un noyau métallique 14, un axe de translation 18a ou 18b à chacune des extrémités 16a ou 16b du noyau et deux bobines électriques 30a et 30b de part et d'autre de l'étrier. Les deux bobines sont reliées à une source de courant continu via des fils électriques 32a et 32 b, de manière à ce que la mise sous tension de l'une des bobines entraîne le déplacement du noyau vers cette bobine. Chacun des axes de translation 18a et 18b passe au travers d'un trou situé à une extrémité de l'étrier 2, l'un des axes 18b étant directement relié à la crémaillère 42, de sorte que la translation du noyau 14 entraîne le déplacement des axes de translation à travers l'étrier 12 et donc la translation de la crémaillère. La translation des axes 18a et 18b est améliorée en fixant des paliers 20a et 20b aux extrémités de l'étrier. Ces paliers comportent un trou de même diamètre que les axes de translation 18a et 18b et sont auto-lubrifiés, de sorte que les axes coulissent au travers des paliers 20a et 20b.The actuating means may comprise an electromagnet which, when activated, allows the element of markup or beacon 2 to pass from one to the other of said first and second positions. In the case where the device 1 comprises a rack gear pair, as shown in FIG. figure 1 , the electromagnet causes the translation of the rack 42. The latter comprises a stirrup 12 intended to be fixed in the ground, a metal core 14, a translation axis 18a or 18b at each of the ends 16a or 16b of the core and two electrical coils 30a and 30b on either side of the stirrup. The two coils are connected to a source of direct current via electrical wires 32a and 32b, so that the energization of one of the coils causes the displacement of the core towards this coil. Each of the translation axes 18a and 18b passes through a hole located at one end of the stirrup 2, one of the axes 18b being directly connected to the rack 42, so that the translation of the core 14 causes the displacement translation axes through the stirrup 12 and thus the translation of the rack. The translation of the axes 18a and 18b is improved by fixing bearings 20a and 20b to the ends of the stirrup. These bearings comprise a hole of the same diameter as the translation axes 18a and 18b and are self-lubricated, so that the axes slide through the bearings 20a and 20b.

Afin d'utiliser un minimum d'énergie, un ressort 22 est fixé d'un côté à l'étrier 12 et de l'autre à un plateau 24 fixé à l'extrémité de l'axe de translation 18a opposé à la crémaillère 42, de manière à ce que le ressort serve de contrepoids à la balise 2. Ainsi la force nécessaire pour soulever la balise 2 est beaucoup plus faible. La suralimentation de la bobine (30a sur la figure 1) permet de générer un champs magnétique suffisant pour exercer la force requise au redressement de la balise 2.In order to use a minimum of energy, a spring 22 is fixed on one side to the stirrup 12 and on the other to a plate 24 fixed to the end of the translation axis 18a opposite the rack 42 , so that the spring serves as a counterweight to the tag 2. Thus the force required to lift the tag 2 is much lower. The supercharging of the coil (30a on the figure 1 ) makes it possible to generate a magnetic field sufficient to exert the force required to recover the beacon 2.

Le dispositif peut également comprendre une ventouse électromagnétique 52 située à l'opposé de la crémaillère 42, de manière à maintenir par aimantation l'axe de translation 18a. Pour cela la ventouse 52 comprend un aimant permanent générant un champs magnétique d'une intensité permettant de maintenir la balise 2 verticale lorsque celle-ci subit une force inférieure à un seuil S, et permettant son rabattement lorsqu'elle subit une contrainte supérieure au seuil S. Ce seuil S est fixé selon les contraintes que peut subir la balise 2. Ainsi, lorsque la balise est en bord de route, il est important que la balise ne se rabatte pas sous l'action du vent. Le seuil S correspondra donc à l'intensité moyenne du vent qui habituellement souffle à l'endroit où la balise doit être implantée. L'aimant permanent est donc choisi en fonction de ce seuil, qui peut également être un seuil standard, tel qu'une résistance à un vent de 20 km/h. Lorsqu'une voiture percute la balise 2 dans le sens de son rabattement dans la première position, la contrainte subit par la balise est supérieure au seuil S ; le choc désolidarise alors l'axe de translation 18a de la ventouse 52. L'entrefer 50 généré est suffisant pour que l'aimant n'exerce plus une force suffisante pour maintenir la balise dans la deuxième position. Cette dernière se rabat alors au niveau du sol. De même lors du rabattement commandé de la balise, la bobine comprise dans la ventouse est alimentée en courant continu au moyen de fils électriques 54 de manière à annuler l'aimantation générée par l'aimant permanent.The device may also comprise an electromagnetic pad 52 located opposite the rack 42, so as to maintain by magnetization the translation axis 18a. For this the suction cup 52 includes a permanent magnet generating a magnetic field of an intensity to maintain the beacon 2 vertical when it undergoes a force below a threshold S, and allowing its folding when it undergoes a stress greater than the threshold S. This threshold S is fixed according to the constraints that may be the tag 2. Thus, when the beacon is on the road, it is important that the beacon does not fall back under the action of wind. The threshold S will therefore correspond to the average intensity of the wind which usually blows at the place where the beacon must be located. The permanent magnet is therefore chosen according to this threshold, which can also be a standard threshold, such as a wind resistance of 20 km / h. When a car hits the beacon 2 in the direction of its folding in the first position, the stress experienced by the beacon is greater than the threshold S; the shock then disengages the translation axis 18a of the suction pad 52. The gap 50 generated is sufficient for the magnet no longer exerts sufficient force to maintain the beacon in the second position. The latter then folds down to the ground level. Similarly during the controlled folding of the beacon, the coil included in the suction cup is supplied with direct current by means of electrical wires 54 so as to cancel the magnetization generated by the permanent magnet.

L'alimentation des bobines est de préférence gérée par un boîtier de commande 34 permettant de synchroniser de manière optimale l'alimentation des bobines 30a, 30b et de la ventouse 52. L'alimentation peut être fournie par une source de courant externe au dispositif ou une source interne, telle qu'une batterie.The supply of the coils is preferably managed by a control box 34 for optimally synchronizing the supply of the coils 30a, 30b and the suction pad 52. The supply can be provided by a current source external to the device or an internal source, such as a battery.

Préférentiellement la balise 2 a une forme permettant de disposer sur son pourtour le ou les moyens de signalisation 5, de sorte que lorsque la balise 2 est redressée, le moyen de signalisation est visible à 360°. Cette forme peut être celle d'un poteau carré, sur chaque face duquel sont fixés le ou les moyens de signalisation. Préférentiellement la balise a la forme d'un poteau à section ronde, le ou les moyens de signalisation étant répartis sur la circonférence de la balise 2. Lorsqu'un boîtier 8 est prévu, celui-ci a de préférence une forme adéquate pour qu'une fois rabattue dans le boîtier, la balise n'ait pas trop de jeu. Par exemple dans le cas d'une balise en forme d'un poteau de section ronde, le boîtier aura la forme d'une gouttière d'un diamètre intérieur identique à celui de la balise.Preferably, the beacon 2 has a shape making it possible to arrange the signaling means or means 5 on its periphery, so that when the beacon 2 is rectified, the signaling means is visible at 360 °. This shape may be that of a square post, on each side of which are fixed the signaling means. Preferably the beacon has the form of a pole to round section, or the signaling means being distributed over the circumference of the tag 2. When a housing 8 is provided, it is preferably of a suitable shape so that once folded into the housing, the beacon n ' For example, in the case of a beacon in the form of a column of round section, the housing will have the shape of a gutter with an inner diameter identical to that of the beacon.

Selon un autre mode de réalisation, la balise 2 est plate et constitue ainsi un couvercle de manière à ce que lorsque la balise est rabattue dans le boîtier 8, la balise recouvre alors le moyen d'actionnement et ferme le boîtier. Ce mode de réalisation peut-être avantageux lorsqu'il est installé directement sur la voie de circulation. En effet, il constitue une fois rabattu en première position un élément sécurisant pour les véhicules à deux roues, qui risquent beaucoup moins de glisser dessus. Dans ce cas, certains moyens de signalisation ne pourront être disposés que sur les deux faces les plus grandes de la balise. Néanmoins, cela n'est pas un inconvénient dans la mesure où ces moyens sont généralement des figures représentatives, tels qu'un stop ou une voie interdite à certains véhicules. En effet dans ce cas, seule une visualisation dans les deux sens de circulation de la route est nécessaire. En revanche, la visualisation à 360° peut être conservée pour des bandes réfléchissantes ou des bandes de diodes qui peuvent être disposées sur l'arrête de la balise. Préférentiellement ces balises plates constituant un couvercle ont une épaisseur de 5 millimètres.According to another embodiment, the beacon 2 is flat and thus constitutes a cover so that when the beacon is folded into the housing 8, the beacon then covers the actuating means and closes the housing. This embodiment may be advantageous when installed directly on the taxiway. Indeed, it is once folded in the first position a secure element for two-wheeled vehicles, which are much less likely to slide on. In this case, some signaling means can be arranged only on the two largest faces of the beacon. Nevertheless, this is not a disadvantage insofar as these means are generally representative figures, such as a stop or a lane prohibited for certain vehicles. Indeed in this case, only a visualization in both directions of circulation of the road is necessary. On the other hand, the 360 ° visualization can be kept for reflective strips or diode strips that can be placed on the edge of the beacon. Preferably these flat tags constituting a cover have a thickness of 5 millimeters.

Les balises sont de préférence conçues pour résister aux contraintes chimiques et de températures propres aux voies de circulation auxquelles elles sont destinées.The beacons are preferably designed to withstand the chemical and temperature constraints specific to the traffic lanes for which they are intended.

Le dispositif selon la présente invention est installé en effectuant un carottage dans le sol. Le trou 10 résultant de ce carottage a une profondeur et un diamètre permettant de loger le moyen d'actionnement et une partie de la balise 2. Une rainure 9 est également effectuée à la surface du sol 3. La rainure 9 débouche dans le carottage et a une profondeur, une largeur et une longueur suffisante pour accueillir la balise 2 lorsque cette dernière est rabattue en première position. La profondeur du trou 10 doit être suffisante pour qu'une fois positionné, l'ensemble du dispositif affleure à la surface du sol 3 lorsque la balise est rabattue. Pour permettre l'évolution des axes de translation 18a et 18b dans l'étrier 12, l'étrier est fixé à une distance suffisante du fond du trou 10.The device according to the present invention is installed by performing a coring in the ground. The hole 10 resulting from this coring has a depth and a diameter making it possible to house the actuation means and a part of the beacon 2. A groove 9 is also made at the ground surface 3. The groove 9 opens into the coring and has a depth, width and length sufficient to accommodate the beacon 2 when the latter is folded to the first position. The depth of the hole 10 must be sufficient so that, once positioned, the entire device is flush with the surface of the ground 3 when the beacon is folded down. To allow the evolution of the translation axes 18a and 18b in the stirrup 12, the stirrup is fixed at a sufficient distance from the bottom of the hole 10.

Ainsi, le moyen d'actionnement est en permanence logé sous la surface et est protégé des véhicules.Thus, the actuating means is permanently housed under the surface and is protected from vehicles.

Dans la figure 1, le dispositif représenté est destiné à être installé après un carottage vertical. Mais le dispositif peut également être prévu pour que le moyen d'actionnement soit installé à l'horizontale. Dans ce cas, la disposition de la crémaillère par rapport aux engrenages permet le rabattement de la balise grâce à une translation horizontale de la crémaillère. Ceci est particulièrement intéressant dans le cas des ponts où la profondeur pour creuser est limitée. Une rainure est effectuée pour accueillir tant la balise rabattue que le moyen d'actionnement. La rainure a une longueur suffisante pour qu'une fois installé, l'ensemble du dispositif affleure à la surface du sol lorsque la balise est rabattue en première position. L'étrier est fixé dans la rainure de manière à permettre l'évolution des axes de translation dans l'étrier.In the figure 1 , the device shown is intended to be installed after vertical coring. But the device can also be provided so that the actuating means is installed horizontally. In this case, the arrangement of the rack relative to the gears allows the folding of the tag through a horizontal translation of the rack. This is particularly interesting in the case of bridges where the depth to dig is limited. A groove is made to accommodate both the folded tag that the actuating means. The groove has a sufficient length that once installed, the entire device is flush with the ground surface when the beacon is folded to the first position. The stirrup is fixed in the groove so as to allow the evolution of the translation axes in the stirrup.

Les applications de ce dispositif sont diverses. Il peut être utilisé pour interdire l'accès à un parking privé. La commande des bobines peut ainsi être actionnée par le propriétaire du parking selon qu'il veut ou non en condamner l'entrée. Pour cela la commande peut être relié à un émetteur récepteur permettant la commande à distance du dispositif.The applications of this device are diverse. It can be used to prohibit access to private parking. The control of the coils can thus be actuated by the owner of the parking according to whether he wants to condemn the entry or not. For this the control can be connected to a transceiver for remote control of the device.

Il peut aussi être utilisé pour prévenir un usager ayant pris une voie à sens de circulation unique dans le mauvais sens. Dans ce cas, la balise 2 est dans la première position, c'est à dire au niveau du sol, si un véhicule est détecté en sens inverse, par un radar ou un agent, celui-ci actionne la commande qui déclenche le redressement de la balise au niveau de la zone ou va passer le véhicule. Le moyen de signalisation 5 indique au passager qu'il est dans le mauvais sens. Ce dispositif permet de placer la balise sur le côté de la voie, mais surtout sur la voie, permettant un signal facilement percevable. La balise peut en effet être percutée par les véhicules quel que soit leur sens de circulation puisque la balise 2 se rabattra au niveau du sol ou se ploiera. Pour améliorer la signalisation, il est également possible d'installer plusieurs dispositifs, selon la présente invention, le long de la voie et à intervalles réguliers.It can also be used to warn a user who has taken a one-way street in the wrong way. In this case, the beacon 2 is in the first position, ie at ground level, if a vehicle is detected in the opposite direction, by a radar or an agent, it activates the command which triggers the recovery of the beacon at the zone where the vehicle will pass. The signaling means 5 indicates to the passenger that he is in the wrong direction. This device allows to place the beacon on the side of the track, but especially on the way, allowing a signal easily collectible. The beacon can indeed be struck by the vehicles regardless of their direction of movement since the beacon 2 will fall back to ground level or will bend. To improve the signaling, it is also possible to install several devices, according to the present invention, along the track and at regular intervals.

Un tel système peut aussi être utilisé sur des voies réservées aux bus ou aux taxis, le moyen de signalisation indiquant le type de véhicule autorisé. Le dispositif peut être installé au milieu de la voie. Dans ce cas, la balise se couche lorsqu'un véhicule passe dessus, et se relève de suite après. Soit le rabattement au niveau du sol se fait dans le sens de la circulation, auquel cas la balise est rabattue dans la première position et le redressement est effectué par le moyen d'actionnement sur commande du chauffeur ou d'un détecteur, soit il se fait dans le sens inverse, auquel cas la balise ploie en se tordant au niveau de l'articulation élastique sous la contrainte du véhicule, frotte sous le véhicule lors de son passage, et se redresse une fois le véhicule passé. Les pare-chocs des véhicules étant en général à 25 ou 35 cm du sol, les dispositifs installés pour ces véhicules comprendront une balise d'environ 45 cm de hauteur, afin que le choc ait lieu dans le quart le plus haut de la balise.Such a system can also be used on lanes reserved for buses or taxis, the signaling means indicating the type of authorized vehicle. The device can be installed in the middle of the track. In this case, the beacon goes down when a vehicle passes over it, and gets up again afterwards. Either the lowering at the ground level is in the direction of the traffic, in which case the beacon is folded in the first position and the rectification is carried out by means of actuation on command of the driver or a detector, or it is in the opposite direction, in which case the beacon bends while twisting at the elastic joint under the constraint of the vehicle, rubs under the vehicle during its passage, and recovers once the vehicle passed. Since vehicle bumpers are generally 25 or 35 cm from the ground, the devices installed for these vehicles will include a marker approximately 45 cm high, so that the impact occurs in the highest quarter of the beacon.

La commande du rabaissement de la balise peut se faire directement de l'extérieur par exemple par l'intermédiaire d'un émetteur relié à un récepteur lui même relié à un module, tel que le boîtier de commande 34, permettant ainsi d'actionner l'alimentation des bobines. On peut aussi prévoir des détecteurs internes à la balise déclenchant l'actionnement de la balise. Par exemple la détection de l'approche d'un véhicule, déclenchera par anticipation le rabaissement de la balise avant tout choc. Ceci permet de prolonger la durée de vie de la balise. Le redressement de la balise peut être programmé au bout d'un certain temps.The control of the lowering of the beacon can be done directly from the outside for example by means of a transmitter connected to a receiver itself connected to a module, such as the control unit 34, allowing to operate the power of the coils. It is also possible to provide detectors internal to the beacon triggering the actuation of the beacon. For example, the detection of the approach of a vehicle, will trigger in anticipation the lowering of the beacon before any shock. This will extend the life of the tag. The recovery of the beacon can be programmed after a certain time.

Une commande interne peut également être utilisée couplée à un dispositif de sûreté afin d'éviter l'échauffement des bobines, dans le cas où la roue d'un véhicule ou tout autre objet empêche le redressement de la balise rabattue au niveau du sol. Le dispositif de sûreté déclenche la commande pendant un temps de déclenchement limité, suffisant pour redresser la balise lorsqu'elle n'est pas bloquée. Si la bobine ne peut pas se redresser, la commande ne sera pas actionnée en continu, évitant ainsi toute surchauffe des bobines. Au bout d'un intervalle de temps supérieur au temps de déclenchement, par exemple huit fois supérieur, le dispositif actionnera à nouveau la commande. L'alternance déclenchement de la commande et intervalle de temps sans actionnement de la commande, se poursuivra tant que la balise ne sera pas redressée.An internal control can also be used coupled to a safety device to prevent heating of the coils, in the case where the wheel of a vehicle or any other object prevents the recovery of the beacon folded at ground level. The safety device triggers the command during a limited tripping time, sufficient to straighten the beacon when it is not blocked. If the spool can not straighten, the control will not be operated continuously, thus avoiding any overheating of the coils. After a time interval greater than the tripping time, for example eight times higher, the device will operate the command again. The alternation triggering of the command and interval of time without actuation of the command, will continue until the beacon is rectified.

Outre sur le réseau routier, ce dispositif peut être utilisé pour des voies ferrées ou des pistes d'aérodromes ou d'aéroports. Dans tous les cas la balise peut être placée au bord des voie, et est levée ou rabattue selon l'événement à signaler. De plus le dispositif peut être placé au milieu de la voie, puisqu'il peut se rabattre dans un sens ou ployer dans l'autre lorsqu'un véhicule passe dessus.In addition to the road network, this device can be used for railways or runways aerodromes or airports. In all cases the beacon can be placed at the edge of the lanes, and is raised or folded depending on the event to report. In addition the device can be placed in the middle of the track, since it can be folded in one direction or bend in the other when a vehicle passes over.
