Description
Dispositif dissuadeur de vitesse pour véhicules automobiles Speed deterrent device for motor vehicles
L'invention concerne un dispositif dissuadeur de vitesse destine a inciter des automobilistes a ralentir leur véhicule automobileThe invention relates to a speed deterrent device intended to encourage motorists to slow down their motor vehicle.
Un bon nombre de chaussées sont équipées de ce qui est communément appelé « ralentisseur » ou « dos d'âne » Ces dispositifs - installés aux endroits sensibles - sont prévus pour inciter les automobilistes a ralentir sous peine de subir - lors de leur franchissement - une forte accélération verticale Cette accélération dépend directement de la géométrie du bossage et varie au carre de la vitesse du véhicule La géométrie de ces ralentisseurs est habituellement réalisée par des couches d enrobes disposées a cet effet II existe également des « ralentisseurs » matérialises par un bossage en caoutchouc ou autres matériaux de synthèseA good number of roadways are equipped with what is commonly called a “speed reducer” or “speed bump”. These devices - installed in sensitive areas - are intended to encourage motorists to slow down under pain of undergoing - when crossing - strong vertical acceleration This acceleration depends directly on the geometry of the boss and varies with the square of the speed of the vehicle The geometry of these retarders is usually carried out by layers of coated intended for this purpose There are also "retarders" materialized by a boss in rubber or other synthetic materials
Par la loi cinématique (en x2), il n existe pas de seuil net entre un franchissement a vitesse autorisée et à vitesse excessive Par exemple, si une vitesse de 72 km/h provoque un gamma de 20 m/s2, une vitesse de 36 km/h induit un gamma non négligeable de 5 m/s2 Les automobilistes respectueux de la loi ne sont donc pas totalement épargnés La nouvelle norme européenne précise la géométrie des « ralentisseurs » afin que soient connues toutes les conséquences dynamiques en fonction de la vitesse (l'accélération et sa dérivée première) Il n'en reste pas moins que cette variation (en x2), de type analogique aurait tout avantage a suivre une loi de type binaire (tout ou rien) La problématique reste posée les élus locaux - qui souhaitent répondre favorablement aux riverains réclamant un ralentisseur - se heurtent à l'opposition des responsables des transports en commun, qui refusent l'inconfort généré par ces ralentisseursBy the kinematic law (in x 2 ), there is no clear threshold between a crossing at authorized speed and at excessive speed For example, if a speed of 72 km / h causes a gamma of 20 m / s 2 , a speed of 36 km / h induces a non-negligible gamma of 5 m / s 2 Law-abiding motorists are therefore not completely spared The new European standard specifies the geometry of the "retarders" so that all the dynamic consequences are known depending on speed (acceleration and its first derivative) The fact remains that this variation (in x 2 ), of analog type would have every advantage to follow a law of binary type (all or nothing) The problem remains posed local elected officials - who wish to respond favorably to local residents claiming a speed bump - face opposition from public transport officials, who refuse the discomfort generated by these speed bumps
L'idée de dissuader l'excès de vitesse par une sélection de type binaire n'est pas nouvelle On peut citer, notamment, le brevet US-4362424 décrivant un dispositif composé d'un boudin transversal rempli par un fluide dont l'échappement dans une chambre appropriée, détermine la valeur du choc transmis au véhicule On connaît également, par le brevet US-3 389677 un dispositif compose d'un boudin transversal antérieur se gonflant par l'air chasse de boudins longitudinaux lors du passage du véhicule On connaît enfin le brevet français 8707663 dont l'idée originale consiste a installer un tapis souple utilisant l'aptitude hydrodynamique de l'eau dans son reseau de tuyaux internes Le drainage dynamique génère par le roulement de I automobile génère ainsi un bossage furtif en sortie du tapis La technique proposée - liée aux fuites hydrauliques en fonction du débit (donc de la vitesse) - suit une loi de variation en fonction du carre de la vitesse avec cependant un effet de seuil à variation de type pseudo-binaire L'inconvénient principal de ces dispositifs réside dans la fragilité des enveloppes souples, face aux diverses agressions de nature chimique et mécanique qu'ils doivent subir Le second inconvénient est lié a la souplesse - par construction - de la chambre a choc, réduisant donc ainsi l'intensité censé être dissuasifThe idea of deterring speeding by binary selection is not new We can cite, in particular, US Pat. No. 4,362,424 describing a device composed of a transverse tube filled with a fluid, the exhaust of which in an appropriate chamber, determines the value of the shock transmitted to the vehicle. Also known from US Pat. No. 3,389,677 is a device composed of an anterior transverse tube inflating with air expels longitudinal tubes during the passage of the vehicle Finally, French patent 8707663 is known, the original idea of which consists in installing a flexible mat using the hydrodynamic ability of the water in its network of internal pipes The dynamic drainage generated by the rolling of the automobile thus generates a furtive boss at the exit of the carpet The proposed technique - linked to hydraulic leaks as a function of the flow rate (and therefore of the speed) - follows a law of variation as a function of the square speed with a pseudo-binary type variation threshold effect The main drawback of these devices lies in the fragility of th flexible envelopes, facing the various chemical and mechanical attacks they must undergo The second drawback is linked to the flexibility - by construction - of the shock chamber, thus reducing the intensity supposed to be dissuasive
La présente invention a pour but de fournir un dispositif dissuadeur de vitesse, robuste et peu deformable, supprimant, pour les véhicules respectant la vitesse autorisée, tous les désagréments consécutifs au franchissement d'un ralentisseur classiqueThe present invention aims to provide a speed deterrent device, robust and not deformable, eliminating, for vehicles respecting the authorized speed, all the inconvenience consecutive to the crossing of a conventional retarder
Le but de l'invention est atteint par un dispositif dissuadeur de vitesse comprenant des moyens mécaniques susceptibles de transmettre aux véhicules qui les franchissent, une forte accélération verticaleThe object of the invention is achieved by a speed deterrent device comprising mechanical means capable of transmitting to vehicles passing through them, strong vertical acceleration
Conformément à l'invention, le dispositif comprend deux dispositifs déclencheurs des moyens mécaniques, placés en amont de ceux-ci et espacés l'un de l'autre dans le sens de leur franchissement de sorte qu'un franchissement des dispositifs déclencheurs par un véhicule en excès de vitesse commande un déplacement des moyens mécaniquesAccording to the invention, the device comprises two devices triggering mechanical means, placed upstream of these and spaced from one another in the direction of their crossing so that a crossing of the trip devices by a speeding vehicle controls movement of mechanical means
Selon des modes de réalisation avantageux de l'invention - chaque déclencheur peut comporter une série de pastilles piézo-electπques ou un film piezo-électπque,According to advantageous embodiments of the invention - each trigger can include a series of piezoelectric pads or a piezoelectric film,
- chaque déclencheur peut être un déclencheur du type électrique tel une boucle à induction capable de générer une impulsion électrique, - chaque déclencheur peut être du type hydraulique- each trigger can be an electric type trigger such as an induction loop capable of generating an electrical pulse, - each trigger can be of the hydraulic type
L'invention consiste en un dispositif dont l'action est de type binaire II diffère également de l'idée du tapis hydrodynamique par son fonctionnement de type essentiellement hydrostatique Le dissuadeur est entièrement autonome du point de vue de l'énergie II ne requiert donc aucune source d'énergie autre que celle qu il prélève aux véhicules qui le franchissentThe invention consists of a device whose action is of binary type II also differs from the idea of the hydrodynamic mat by its essentially hydrostatic type operation. The deterrent is entirely autonomous from the point of view of energy II therefore requires no source of energy other than that which it takes from vehicles passing through it

Les figures 9 à 11 représentent d'autres détails du dispositif de l'inventionFigures 9 to 11 show other details of the device of the invention
Dans sa version de base (figure 1), le dispositif comporte deux dispositifs déclencheurs 1 placés en amont de la plate-forme de dissuasion 2. Chaque déclencheur 1 est constitué d'un joint (figure 9) comportant une série de pastilles piezo-électπques (ou un film piezo-électπque tel que le PVDF), qui, soumisent à la pression exercée par le passage des véhicules, génèrent une impulsion électrique La mesure de l'écart de temps entre les deux impulsions sur les déclencheurs placés l'un derrière l'autre, est ainsi exploitée par une carte électronique destinée à commander le mouvement de la plate-forme 2 Cette dernière est normalement en position haute c'est-à-dire offrant, comme le montre la figure 1, un passage plat aux usagers qui respectent la vitesse prescrite Dans le cas contraire (avec une fréquence statistiquement faible), l'action combinée des déclencheurs 1 et d'une batterie d'accumulateurs permet d'actionner (pour un temps) la rétraction des vérins 3, puis d'assurer leur remontée en position normaleIn its basic version (Figure 1), the device includes two trigger devices 1 placed upstream of the deterrent platform 2. Each trigger 1 consists of a seal (Figure 9) comprising a series of piezoelectric pads (or a piezoelectric film such as PVDF), which, subject to the pressure exerted by the passage of vehicles, generate an electric pulse La measurement of the time difference between the two pulses on the triggers placed one behind the other, is thus exploited by an electronic card intended to control the movement of the platform 2 The latter is normally in the high position c ' that is to say offering, as shown in Figure 1, a flat passage to users who respect the prescribed speed Otherwise (with a statistically low frequency), the combined action of triggers 1 and a battery of accumulators used to actuate (for a time) the retraction of the jacks 3, then to ensure their ascent to the normal position
La plate-forme 2 comporte (figure 3) deux volets 4, 5, articulée aux extrémités 6 et en appui sur les bords du bossage 8 Le bossage 8 est fixé sur une série de vérins hydrauliques 3The platform 2 comprises (FIG. 3) two flaps 4, 5, articulated at the ends 6 and bearing on the edges of the boss 8 The boss 8 is fixed on a series of hydraulic cylinders 3
La figure 4 montre le détail d'une des articulations 6 Cette articulation est composée d'un support usiné 10 dans lequel repose le rond 9 soudé au volet 4 (ou 5) L'élément de châssis 12 soutient le profilé 11 (noyé dans le béton) sur lequel est positionne et fixé le support d'articulation 10Figure 4 shows the detail of one of the articulations 6 This articulation is composed of a machined support 10 in which rests the round 9 welded to the flap 4 (or 5) The chassis element 12 supports the profile 11 (embedded in the concrete) on which the articulation support 10 is positioned and fixed
La figure 3 montre que l'ensemble plate-forme de dissuasion est encastré dans la chaussée Le châssis du dispositif dissuadeur collabore avec des plots en béton pour assurer la stabilité de l'ensemble Les plots de béton sont réalises selon une géométrie telle qu'ils servent de butées extrêmes en renfort a la propre inertie des volets 4 et 5Figure 3 shows that the deterrent platform assembly is embedded in the roadway The chassis of the deterrent device works with concrete studs to ensure the stability of the set The concrete studs are made according to a geometry such that serve as extreme stops in reinforcement to the own inertia of flaps 4 and 5
Les veπns 3 sont reliés via l'électrovanne 18 (figure 5) à un accumulateur hydraulique 16 La charge de l'accumulateur hydraulique 16 est assurée par un des dispositifs de déclenchement via des clapets 30, 31The veπns 3 are connected via the solenoid valve 18 (Figure 5) to a hydraulic accumulator 16 The hydraulic accumulator 16 is charged by one of the triggering devices via valves 30, 31
L'ensemble dissuadeur ainsi décrit, ne concerne qu'une voie -ou un sens de circulation - de la chaussée La plate¬ forme de dissuasion 2 est recouverte d'une bande souple, tendue et armée 7 dont le rôle est multiple a) assurer l'étancheité, b) assurer la continuité mécanique de roulement, c): amoindrir les émissions sonores, d) supprimer les éventuels jeux aux appuis des volets, e)' ajuster le coefficient de frottement offert aux pneumatiques des véhicules et enfin réaliser une pièce d'usure pour préserver le dispositif qu'elle recouvre. Dans sa version de base, le dispositif relatif à cette demande de brevet, ne requiert: 1) aucune source d'énergie autre que celle transmise par le passage des véhicules, 2) i comprend les déclencheurs 1 décrits précédemment La figure 5 montre également que le bossage 8 est équipé de plusieurs vérins 3 fixés sur une plaque 14 figure 5 et figure 6 qui montrent en partie une vue de dessous du bossage 8 Chaque vérin 3 comporte, fixée sur l'extrémité de sa tige, une plaque 15 qui se trouve donc intercalée entre les deux appuis des volets 4 et 5 sur le bossage 8 La figure 5 montre également une bâche 17 (contenant le fluide hydraulique) et un limiteur de pression 19The deterrent assembly thus described, relates only to one lane - or one direction of movement - of the roadway. The deterrent platform 2 is covered with a flexible, taut and armed strip 7 whose role is multiple a) ensuring watertightness, b) ensuring the mechanical continuity of bearing, c): reduce noise emissions, d) eliminate any play on the flap supports, e) 'adjust the coefficient of friction offered to vehicle tires and finally make a wearing part to preserve the device it covers . In its basic version, the device relating to this patent application does not require: 1) any source of energy other than that transmitted by the passage of vehicles, 2) i comprises the triggers 1 described previously Figure 5 also shows that the boss 8 is equipped with several jacks 3 fixed on a plate 14 in FIG. 5 and in FIG. 6 which partially show a bottom view of the boss 8 Each jack 3 comprises, fixed on the end of its rod, a plate 15 which is therefore interposed between the two supports of the flaps 4 and 5 on the boss 8 FIG. 5 also shows a tank 17 (containing the hydraulic fluid) and a pressure limiter 19
Le fonctionnement est le suivant (figures 5, 7 et 8) Si le temps séparant les deux signaux électriques (C1 et C2) figure 8, entre les déclencheurs 1 est supérieur à un temps de référence (dt), les volets 4 et 5 restent dans leur position normale et le franchissement est à l'aise Si ce temps est inférieur au temps de référence dt (figure 8), le dispositif « traitement du signal » 41 (figure 7) commande aussitôt l'électrovanne 18 en utilisant l'énergie de la batterie. Cette brève impulsion électrique à l'électrovanne 18 est relayée par un dispositif classique de temporisation hydraulique pour le retour à i'état repos. De ce fait, les vérins 3 se rétractent en se vidangeant dans la bâche 17 Le véhicule doit donc subir le choc relatif à l'accélération générée par la géométrie de type « cassis » L'analyse du fonctionnement (figure 8) montre qu'un temps (tp) est nécessaire pour réinitialiser le cycle (espace-temps normal entre deux véhicules). La figure 7 montre que lorsque l'électrovanne retourne en position normale, l'accumulateur permet le remplissage à nouveau de la chambre inférieure du vérin 3 Dans tous les cas de passage de véhicule, les vérins 13 subissent un déplacement vertical Ce mouvement est exploité pour pomper du fluide hydraulique de la bâche 17 vers l'accumulateur 16. La figure 7 montre que le clapet 20 doit se fermer lors de la descente des vérins 13 et que le clapet 21 doit alors s'ouvrir pour assurer la recharge de l'accumulateur 16 Lors de la remontée des vérins 13 par leur ressort interne, la position des clapets est inversée et le fluide est aspiré de la bâche 17 La régulation de pression est assurée par le limiteur 19.The operation is as follows (Figures 5, 7 and 8) If the time separating the two electrical signals (C1 and C2) in Figure 8, between the triggers 1 is greater than a reference time (dt), the flaps 4 and 5 remain in their normal position and the crossing is comfortable If this time is less than the reference time dt (Figure 8), the "signal processing" device 41 (Figure 7) immediately controls the solenoid valve 18 using energy drums. This brief electrical pulse to the solenoid valve 18 is relayed by a conventional hydraulic time delay device for returning to the idle state. As a result, the jacks 3 retract while emptying into the cover 17. The vehicle must therefore be subjected to the shock relating to the acceleration generated by the geometry of the "blackcurrant" type. The analysis of the operation (FIG. 8) shows that a time (tp) is required to reset the cycle (normal space-time between two vehicles). Figure 7 shows that when the solenoid valve returns to the normal position, the accumulator allows the refilling of the lower chamber of the jack 3 In all cases of vehicle passage, the jacks 13 undergo a vertical displacement This movement is used to pump hydraulic fluid from the tank 17 to the accumulator 16. FIG. 7 shows that the valve 20 must close when the cylinders 13 are lowered and the valve 21 must then open to ensure the recharging of the accumulator 16 When the cylinders 13 are raised by their internal spring, the position of the valves is reversed and the fluid is drawn from the tank 17 The pressure regulation is ensured by the limiter 19.
La figure 8 montre également que l'énergie piézo¬ électrique des déclencheurs 1 est récupérée pour charger la batterie d'accumulateurs Bien que l'énergie piézo-électπque soit très faible, ce dispositif est réaliste car la commande de l'électrovanne qui n'intervient que très rarement est de courte durée Un simple calcul permet de conclure que la batterie serait efficace durant plusieurs années même sans cette mini¬ charge (compensation) La figure 9 montre une coupe du profilé isolant (moulé ou extrudé), assemblé classiquement et symétriquement par deux joncs. La vue en élévation montre que le profilé isolant 24 comporte une série de perforations destinées à recevoir les mini-tubes piézo-electπques 23. Les profilés métalliques 22, disposés de part et d'autre des dipôles piezo-électπques servent à la fois de raidisseurs mécaniques et d'électrodes pour les dipôles Les tubes piézo¬ électriques peuvent être remplacés par tout autre matériau piézo-électπque (film PVDF ou autre)FIG. 8 also shows that the piezoelectric energy of the triggers 1 is recovered to charge the storage battery. Although the piezoelectric energy is very low, this device is realistic because the control of the solenoid valve which does not intervenes that very rarely is of short duration A simple calculation allows to conclude that the battery would be effective for several years even without this mini¬ charge (compensation) Figure 9 shows a section of the insulating profile (molded or extruded), assembled conventionally and symmetrically by two rods. The elevation view shows that the insulating profile 24 comprises a series of perforations intended to receive the piezoelectric mini-tubes 23. The metal profiles 22, arranged on either side of the piezoelectric dipoles serve both as stiffeners mechanical and electrodes for the dipoles The piezoelectric tubes can be replaced by any other piezoelectric material (PVDF film or other)
Dans une première variante la version de base relative à cette demande de brevet, comporte en lieu et place du déclencheur 1 de tube piézo, un déclencheur de type électrique (bouche à induction classique ou tout autre dispositif) capable de générer une impulsion électrique.In a first variant, the basic version relating to this patent application, instead of the trigger 1 of the piezo tube, an electrical type trigger (conventional induction mouth or any other device) capable of generating an electrical pulse.
Dans une seconde variante, le dispositif dissuadeur selon la version de base, utilise l'ensemble des vérins 13, reliés entre eux par un tube 28, comme déclencheur 1 de type hydraulique en lieu et place des déclencheurs 1 de type électrique Outre la fonction de regonflage de l'accumulateur hydraulique, ces deux déclencheurs de type hydraulique, sont utilisés pour la mesure de l'écart temps, le séquencement logique et l'action de commande de la vanne de commande des vérins 3 La figure 10 montre ce type de déclencheur hydraulique encastré dans la chaussée, comportant des mini- véπns hydrauliques 25 aptes à fournir une énergie de type hydraulique Le déclencheur 1-a actionné le premier, actionne la vanne 26 ouvrant ainsi le circuit entre le déclencheur 1-b et la commande de la vanne 27 Le retour en position repos est ajustable par le temps dt si l'impulsion sur le déclencheur 1-b suit celle de 1-a dans un temps inférieur à dt, cette impulsion actionne la commande de la vanne 27 et ainsi la descente des volets 4 et 5 Le schéma de la figure 10 montre que le déclencheur 1-b joue e même rôle que décrit précédemment s'agissant du regonflage de l'accumulateur hydraulique 16In a second variant, the deterrent device according to the basic version, uses all of the jacks 13, connected together by a tube 28, as trigger 1 of the type hydraulic instead of electric type triggers 1 In addition to the re-inflation function of the hydraulic accumulator, these two hydraulic type triggers are used for time difference measurement, logical sequencing and control action of the actuator control valve 3 FIG. 10 shows this type of hydraulic actuator built into the roadway, comprising hydraulic mini-valves 25 capable of supplying energy of the hydraulic type The actuator 1-actuated first, actuates the valve 26 opening thus the circuit between the trigger 1-b and the control of the valve 27 The return to the rest position is adjustable by the time dt if the pulse on the trigger 1-b follows that of 1-a in a time less than dt, this pulse actuates the control of the valve 27 and thus the descent of the flaps 4 and 5 The diagram in FIG. 10 shows that the trigger 1-b plays the same role as described above with regard to the re-inflating hydraulic accumulator age 16
La figure 11 montre que les mmi-véπns assurant la fonction cumulée « déclencheur et regonflage de l'accumulateur hydraulique » sont remplacés, en variante de type hydraulique à tube, par un tube souple 29 aménagé dans le profilé du déclencheur 1 L'énergie des véhicules le franchissant est ainsi transformée en énergie de type hydraulique Les signes de référence insérés après les caractéristiques techniques mentionnées dans les revendications, ont pour seul but de faciliter la compréhension de ces dernières, et n'en limitent aucunement la portée FIG. 11 shows that the mmi-véπns ensuring the cumulative function "trigger and re-inflation of the hydraulic accumulator" are replaced, as a variant of the hydraulic tube type, by a flexible tube 29 arranged in the profile of the trigger 1 The energy of vehicles crossing it are thus transformed into hydraulic type energy. The reference signs inserted after the technical characteristics mentioned in the claims, have the sole purpose of facilitating the understanding of the latter, and in no way limit their scope.
