Description

L'invention porte sur un dispositif de ramassage d'objets sur une chaussée, ainsi que sur un véhicule de type fourgon équipé d'un tel dispositif.The invention relates to a device for collecting objects on a roadway, as well as a van-type vehicle equipped with such a device.

Les objets qui gisent sur la chaussée d'une route ou autoroute constituent un danger important pour la circulation. Parmi ces objets on peut citer les éclats de pneumatique, les enjoliveurs de roue, des marchandises perdues par des véhicules de transport, etc.Objects lying on the roadway of a road or highway constitute a significant danger to traffic. These objects include tire splinters, wheel trims, goods lost by transport vehicles, etc.

Généralement, ces objets sont ramassés manuellement par un opérateur (patrouilleur) qui se rend sur le site à bord d'un véhicule, gare ledit véhicule sur la bande d'arrêt d'urgence de l'autoroute ou sur le bord de la route, descend du véhicule et traverse à pieds la chaussée. Cette opération comporte un risque de collision entre l'opérateur et les véhicules circulant sur les voies de l'autoroute ou de la route, et de temps à autre elle peut être à l'origine d'accidents occasionnant des blessures graves ou le décès de l'opérateur.Generally, these objects are picked up manually by an operator (patroller) who goes to the site in a vehicle, park the vehicle on the emergency stop strip of the highway or on the roadside, gets off the vehicle and crosses the road. This involves a risk of collision between the operator and the vehicles traveling on the highway or road lanes, and from time to time can lead to accidents resulting in serious injury or death. the operator.

Le document US 2006/0145489 enseigne qu'il est possible de ramasser des objets d'une chaussée à l'aide d'une pelleteuse dont le godet est équipé, en sa partie inférieure, d'un sabot en matière élastique destinée à rentrer en contact avec la surface de la chaussée. Cependant, l'épaisseur de ce sabot constitue un obstacle à un ramassage efficace des objets. En outre, une pelleteuse se déplace généralement beaucoup plus lentement que les autres véhicules circulant sur une autoroute, et constitue de ce fait une gêne, voire un danger, pour la circulation. Voir aussi DE 91 12 470 U1 .The document US 2006/0145489 teaches that it is possible to pick up objects from a roadway using an excavator whose bucket is equipped, in its lower part, with a shoe of elastic material intended to come into contact with the surface of the floor. However, the thickness of this shoe is an obstacle to an efficient collection of objects. In addition, an excavator usually moves much more slowly than other vehicles traveling on a highway, and is therefore an inconvenience, even a danger, for traffic. See as well DE 91 12 470 U1 .

Les documents US 5,596,784 et US 5,745,947 divulguent des véhicules spécialement adaptés au ramassage d'objets d'une chaussée. Il s'agit de machines complexes et coûteuses. Concrètement, l'exploitant d'un réseau routier ou autoroutier ne pourrait disposer que d'un nombre très limités de ces machines, qui ne seraient donc pas en l'état d'intervenir rapidement dès le signalement d'un objet sur une chaussée. Or, la rapidité de l'intervention est essentielle pour assurer la sécurité des usagers du réseau.The documents US 5,596,784 and US 5,745,947 disclose vehicles specially adapted for picking up objects from a roadway. These are complex and expensive machines. Specifically, the operator of a road or highway network could have only a very limited number of these machines, which would not be able to intervene quickly as soon as an object is reported on a roadway. However, the speed of the intervention is essential to ensure the safety of users of the network.

Le document KR 2002/0082034 divulgue un dispositif de ramassage d'objets sur une chaussée comportant un plateau de ramassage destiné à être monté au-dessous d'un véhicule à moteur, ainsi que des moyens d'actionnement permettant de faire passer ledit plateau, par translation verticale, d'une position relevée non opérationnelle à une position abaissée de ramassage et inversement. Un tel dispositif présente l'inconvénient de ne pouvoir être installé que sur un véhicule de type poids-lourd : en effet, la hauteur du sol d'un véhicule léger serait insuffisante pour permettre le montage d'un plateau de ramassage et son déplacement vertical, sauf à sacrifier de manière excessive ses dimensions, et donc celles des objets pouvant être ramassés. On retrouve donc, bien que de manière moins marquée, l'un des inconvénients mentionnés à propos des documents US 5,596,784 et US 5,745,947 , à savoir la difficulté de disposer d'un parc suffisant de véhicules de ramassage, permettant des interventions rapides en tout point d'un réseau routier ou autoroutier.The document KR 2002/0082034 discloses a device for collecting objects on a roadway comprising a pickup platform intended to be mounted beneath a motor vehicle, as well as actuating means for moving said platform, by vertical translation, of a raised position that is not operational at a lowered pick up position and vice versa. Such a device has the disadvantage of being able to be installed only on a vehicle type heavyweight: indeed, the height of the ground of a light vehicle would be insufficient to allow the mounting of a collection tray and its vertical movement , except to sacrifice excessively its dimensions, and therefore those objects that can be collected. Thus, although less markedly, one of the disadvantages mentioned in the documents US 5,596,784 and US 5,745,947 , namely the difficulty of having a sufficient fleet of collection vehicles, allowing rapid interventions at any point of a road or motorway network.

L'invention vise à résoudre les inconvénients précités de l'art antérieur.The invention aims to solve the aforementioned drawbacks of the prior art.

Conformément à l'invention, ce but est atteint par un dispositif de ramassage d'objets sur une chaussée comportant un plateau de ramassage, des moyens de fixation dudit plateau à un véhicule terrestre à moteur et des moyens d'actionnement pour faire passer ledit plateau d'une position relevée non opérationnelle à une position abaissée de ramassage et inversement ; caractérisé en ce que : lesdits moyens de fixation sont adaptés pour permettre la fixation dudit plateau de ramassage à l'avant d'un véhicule terrestre à moteur ; et en ce que lesdits moyens d'actionnement sont adaptés pour faire pivoter ledit plateau de ramassage entre ladite position relevée, dans lequel il est orienté perpendiculairement à la surface de la chaussée, et ladite position abaissée, dans laquelle il est sensiblement parallèle à la surface de la chaussée.According to the invention, this object is achieved by a device for collecting objects on a roadway comprising a pickup platform, means for fixing said platform to a land motor vehicle and actuating means for passing said platform. from a non-operative raised position to a lowered pickup position and vice versa; characterized in that: said securing means is adapted to allow attachment of said pickup tray to the front of a land motor vehicle; and in that said actuating means are adapted to pivot said pickup tray between said raised position, in which it is oriented perpendicular to the surface of the carriageway, and said lowered position, in which it is substantially parallel to the surface of the roadway.

Comme le plateau de ramassage est monté à l'avant, et pas au-dessous, du véhicule, ce dernier peut être de type léger sans avoir à sacrifier la contenance du plateau. Ainsi, un dispositif de ramassage selon l'invention pourrait être monté sur tous les fourgons utilisés par les patrouilleurs d'un tronçon autoroutier, permettant des interventions extrêmement rapides.As the pickup plate is mounted at the front, and not below, the vehicle, the latter can be light type without sacrificing the capacity of the tray. Thus, a collection device according to the invention could be mounted on all the vans used by the patrol boats of a highway section, allowing extremely fast interventions.

En outre, le plateau de ramassage du dispositif du document KR 2002/0082034 fait saillie depuis l'avant du véhicule lorsqu'il se trouve dans sa position relevée. A l'évidence, cet agencement est dangereux pour les autres usagers de la route, notamment en cas de collision. Le dispositif de l'invention ne présente pas cet inconvénient.In addition, the pickup tray of the document device KR 2002/0082034 protrudes from the front of the vehicle when in its raised position. Obviously, this arrangement is dangerous for other road users, especially in the event of a collision. The device of the invention does not have this disadvantage.

Selon des modes de réalisation particuliers de l'invention :

  • Le dispositif de ramassage peut comporter également un détecteur pour mesurer la distance du plateau de ramassage de la chaussée, et un système d'asservissement pour maintenir constante ladite distance lorsque le plateau se trouve dans sa position abaissée de ramassage. Typiquement, une distance de l'ordre de 1 cm est adaptée.
  • Ledit plateau de ramassage peut comporter au moins une roue destinée à être en contact avec la chaussée lorsqu'il se trouve dans sa position abaissée de ramassage.
  • En variante, ledit plateau de ramassage peut être agencé de telle manière que, lorsqu'il se trouve dans sa position abaissée de fonctionnement, au moins une partie avant de son fond frotte sur la chaussée.
  • Le plateau de ramassage peut comporter au moins deux bavettes formant un entonnoir pour guider des objets à ramasser vers l'intérieur dudit plateau. Avantageusement, lesdites bavettes peuvent être montées pivotantes pour passer d'une position repliée, lorsque le plateau de ramassage se trouve dans sa position relevée non opérationnelle, à une position dépliée, lorsque le plateau de ramassage se trouve dans sa position abaissée de ramassage. Le dispositif du document KR 2002/0082034 ne présente pas un tel entonnoir, qui pourrait difficilement être logé sous le véhicule sans risquer de venir en contact avec les roues de ce dernier.
  • Le plateau de ramassage peut être équipé d'un rouleau-brosse fixé à sa partie supérieure.
  • En variante ou en complément, le plateau de ramassage peut être équipé d'au moins une butée, située en sa partie antérieure, montée pivotante de manière à permettre l'entrée d'un objet dans le plateau mais d'empêcher sa sortie accidentelle.
  • Lesdits moyens d'actionnement peuvent être adaptés pour orienter et/ou déplacer latéralement le plateau de ramassage lorsqu'il se trouve dans sa position abaissée de ramassage. Cela permet, notamment, d'utiliser le plateau de ramassage pour pousser vers le bord de la chaussée un objet trop grand pour être ramassé. Là encore, cette caractéristique serait incompatible avec une fixation du plateau de ramassage au-dessous du véhicule.
  • Le plateau de ramassage peut être pourvu de moyens pour absorber l'énergie cinétique des objets ramassés et empêcher leur expulsion, par rebondissement, dudit plateau.
  • Le plateau de ramassage peut être pourvu également d'un élément de fermeture supérieure, de préférence élastique. Avantageusement, ledit élément de fermeture supérieure peut être monté en translation sur le plateau de ramassage, de manière à se rapprocher du fond dudit plateau lorsque ce dernier passe dans sa position relevée et à s'éloigner dudit fond lorsque le plateau passe dans sa position abaissée.
According to particular embodiments of the invention:
  • The pickup device may also include a sensor for measuring the distance from the pickup tray of the carriageway, and a servo system for maintaining said distance constant when the tray is in its lowered pickup position. Typically, a distance of the order of 1 cm is adapted.
  • Said pickup plate may comprise at least one wheel intended to be in contact with the roadway when it is in its lowered pickup position.
  • Alternatively, said pickup tray may be arranged such that, when in its lowered operating position, at least a front portion of its bottom rubs on the carriageway.
  • The collection tray may comprise at least two flaps forming a funnel for guiding objects to be picked up towards the inside of said tray. Advantageously, said flaps may be pivotally mounted to move from a folded position, when the pickup tray is in its non-operative raised position, to an unfolded position, when the pickup tray is in its lowered pickup position. The device of the document KR 2002/0082034 does not have such a funnel, which could hardly be housed under the vehicle without the risk of coming into contact with the wheels of the latter.
  • The picking plate can be equipped with a brush roll fixed at its upper part.
  • Alternatively or additionally, the pickup plate may be equipped with at least one stop, located in its front part, pivotally mounted so as to allow the entry of an object in the tray but to prevent accidental exit.
  • Said actuating means may be adapted to orient and / or move laterally the pickup tray when in its lowered pickup position. This allows, in particular, to use the pickup tray to push towards the edge of the floor an object too large to be picked up. Again, this feature would be incompatible with a fixing of the pickup tray below the vehicle.
  • The collection tray may be provided with means for absorbing the kinetic energy of the collected objects and prevent their expulsion, by rebounding, said tray.
  • The pickup tray may also be provided with a top closure member, preferably resilient. Advantageously, said upper closure member can be mounted in translation on the pickup tray, so as to approach the bottom of said tray when the latter passes in its raised position and to move away from said bottom when the tray passes into its lowered position. .

Un autre objet de l'invention est un véhicule terrestre à moteur de type fourgon comportant un tel dispositif de ramassage d'objets sur une chaussée, ainsi que des moyens de commande des actionneurs dudit dispositif. Avantageusement, le plateau de ramassage d'objets peut être fixé entre les phares du véhicule de manière à se positionner devant la calandre de ce dernier lorsqu'il se trouve dans sa position relevée.Another object of the invention is a van-type land motor vehicle comprising such a device for picking up objects on a roadway, as well as means for controlling the actuators of said device. Advantageously, the object collecting plate can be fixed between the headlights of the vehicle so as to be positioned in front of the calender of the latter when it is in its raised position.

D'autres caractéristiques, détails et avantages de l'invention ressortiront à la lecture de la description faite en référence aux dessins annexés donnés à titre d'exemple et qui représentent, respectivement :

Other characteristics, details and advantages of the invention will emerge on reading the description given with reference to the accompanying drawings given by way of example and which represent, respectively:
  • The figure 1 a side view of the front portion of a van equipped with a pickup device according to a first embodiment of the invention in its non-operative raised position;

Le dispositif 1 de ramassage d'objets selon l'invention comprend un plateau de ramassage 10 comportant un fond 10a, deux rebords latéraux ou flancs 10b, une paroi de fond 10c et une fermeture supérieure 10d du plateau, optionnelle. Un filet 17 peut être tendu sur le fond 10a et devant la paroi de fond 10c afin d'absorber l'énergie cinétique des objets ramassés, pour éviter qu'ils ne rebondissent et soient par conséquent éjectés à l'extérieur du plateau. Cela permet d'effectuer le ramassage à une vitesse relativement importante, de l'ordre de 50 - 60 km/h ou plus. D'autres moyens d'absorption d'énergie cinétique, tel qu'un rembourrage en mousse, peuvent également être envisagés.The device 1 for collecting objects according to the invention comprises a pickup plate 10 having a bottom 10a, two side edges or flanks 10b, a bottom wall 10c and an upper closure 10d of the plate, optional. A net 17 can be stretched on the bottom 10a and in front of the bottom wall 10c in order to absorb the kinetic energy of the collected objects, to prevent them from bouncing and are therefore ejected outside the plate. This makes it possible to carry out the collection at a relatively high speed, of the order of 50 - 60 km / h or more. Other means of absorbing kinetic energy, such as foam padding, can also be envisaged.

La fermeture supérieure 10d peut être constituée par un capot ou, plus avantageusement, par un filet constitué de câbles élastiques et/ou de sangles élastiques. Il est avantageux que la distance qui sépare l'élément de fermeture supérieure 10d du fond 10a du plateau de ramassage 10 soit variable. En particulier, lorsque le plateau pivote vers sa position relevée, ledit élément de fermeture supérieure peut se rapprocher du fond, pour minimiser l'encombrement du dispositif ; inversement, lorsque le plateau pivote vers sa position abaissée, cet élément peut s'éloigner du fond pour permettre le ramassage d'objets de dimensions importantes. Ce mouvement peut être commandé par des actionneurs ou, de préférence, être obtenu de manière passive à l'aide d'éléments élastiques tels que des ressorts.The upper closure 10d may be constituted by a cover or, more advantageously, by a thread consisting of elastic cables and / or elastic straps. It is advantageous that the distance separating the upper closure member 10d from the bottom 10a of the pickup plate 10 is variable. In particular, when the plate pivots to its raised position, said upper closure element can be closer to the bottom, to minimize the size of the device; conversely, when the plateau rotates towards its lowered position, this element can move away from the bottom to allow the pickup of large objects. This movement can be controlled by actuators or, preferably, be obtained passively by means of elastic elements such as springs.

Dans un premier mode de réalisation de l'invention (figures 1 et 2) un rouleau-brosse 16 peut être disposé au-dessus du plateau de ramassage 10, soutenu par deux bras orientés parallèlement au fond 10. Ces bras peuvent être adaptés pour permettre un certain déplacement vertical du rouleau-brosse 16 par rapport au fond 10a du plateau, afin de permettre le ramassage d'objets de dimensions importantes.In a first embodiment of the invention ( Figures 1 and 2 ) a brush roll 16 can be disposed above the pickup tray 10, supported by two arms oriented parallel to the bottom 10. These arms can be adapted to allow some vertical movement of the brush roll 16 relative to the bottom 10a of the tray, to allow the collection of large objects.

Sur la figure 2, la flèche R indique le sens de rotation de ce rouleau-brosse, actionné par un moteur électrique, qui permet de faciliter le ramassage d'un objet 2 gisant sur la chaussée 3, et d'empêcher son expulsion accidentelle du plateau 10.On the figure 2 , the arrow R indicates the direction of rotation of this brush roller, powered by an electric motor, which makes it easier to pick up an object 2 lying on the roadway 3, and to prevent its accidental expulsion from the plate 10.

Dans un deuxième mode de réalisation de l'invention (figures 3 à 7 le rouleau-brosse 16 est remplacé par une butée ou un ensemble de butées pivotantes, situées à l'avant du plateau et permettant l'entrée d'objets dans ledit plateau mais en empêchant la sortie.In a second embodiment of the invention ( Figures 3 to 7 the brush roll 16 is replaced by a stop or a set of pivoting stops, located at the front of the tray and allowing the entry of objects into said tray but preventing the exit.

Dans l'exemple des figures 3 à 7, l'ensemble de butées est constitué par une pluralité de tiges 160 pivotantes autour d'un axe horizontal et montées sur une barre horizontale 161 orientée en travers du plateau. Les tiges 160 peuvent pivoter librement vers l'arrière lorsque le plateau se relève (voir la figure 3) ou lorsqu'un objet est ramassé ; en revanche leur pivotement vers l'avant est limité, de manière à empêcher la sortie accidentelle d'un objet contenu dans le plateau (voir les figures 4 et 7). On comprend que les tiges 160 pourraient être remplacées par des butées de forme différente, par exemple des plaques ; ces butées pourraient également être articulées au fond du plateau ou à ses flancs, et comporter un élément élastique de rappel tel qu'un ressort.In the example of Figures 3 to 7 , the set of stops is constituted by a plurality of rods 160 pivoting about a horizontal axis and mounted on a horizontal bar 161 oriented across the plate. The rods 160 can pivot freely backward when the tray rises (see figure 3 ) or when an object is picked up; on the other hand, their forward pivoting is limited, so as to prevent the accidental exit of an object contained in the plate (see figures 4 and 7 ). It is understood that the rods 160 could be replaced by stops of different shape, for example plates; these stops could also be articulated at the bottom of the tray or at its flanks, and include a resilient biasing element such as a spring.

La figure 4 montre un ensemble de butées pivotantes 170 en forme de dents, fonctionnant comme des clapets anti-retour, articulées au fond du plateau. Elles empêchent notamment que des objets de petites dimensions ne puissent sortir du plateau en passant au-dessous des tiges 160.The figure 4 shows a set of pivoting stops 170 in the form of teeth, functioning as check valves, hinged to the bottom of the tray. In particular, they prevent small objects dimensions can not get out of the tray passing under the rods 160.

La barre horizontale 161 ne supporte pas seulement les butées 160, mais également le côté avant du filet élastique 10d constituant l'élément de fermeture supérieur du plateau 10.The horizontal bar 161 not only supports the stops 160, but also the front side of the elastic thread 10d constituting the upper closure element of the plate 10.

On peut observer sur les figures 3, 4 et 7 que cette barre horizontale 161 est portée par deux barres verticales 162 montées coulissantes à l'intérieur de guides 163 ; un ressort situé à l'intérieur de ces guides pousse les barres verticales 162 vers l'extérieur. Lorsque le plateau se trouve en sa position relevée, les barres verticales 162 sont forcées à l'intérieur des guides 163, contre l'action de ces ressorts : l'encombrement du dispositif se trouve ainsi minimisé. Inversement, lorsque le plateau se trouve en sa position abaissée, lesdits ressorts poussent les barres verticales 162 à l'extérieur des guides, éloignant ainsi la barre horizontale 161 et l'élément de fermeture supérieur du fond du plateau, pour maximiser l'ouverture de ce dernier et permettre le ramassage d'objets de grandes dimensions.We can observe on Figures 3, 4 and 7 that this horizontal bar 161 is carried by two vertical bars 162 mounted sliding inside guides 163; a spring located within these guides pushes the vertical bars 162 outward. When the tray is in its raised position, the vertical bars 162 are forced inside the guides 163, against the action of these springs: the size of the device is thus minimized. Conversely, when the tray is in its lowered position, said springs push the vertical bars 162 outside the guides, thus moving the horizontal bar 161 and the upper closure element away from the bottom of the tray, to maximize the opening of the tray. the latter and allow the collection of large objects.

L'ensemble barre 161/tiges 160 n'a pas été représenté sur les figures 5 et 6 pour des raisons de clarté. De même, le filet absorbeur d'énergie 17 n'est pas représenté sur les figures 5 et 7 afin de ne pas les surcharger.The bar 161 / rod 160 assembly has not been shown on the Figures 5 and 6 for the sake of clarity. Similarly, the energy absorbing net 17 is not represented on the figures 5 and 7 in order not to overload them.

Le plateau de ramassage 10 est fixé à la partie avant d'un véhicule terrestre à moteur 4, tel qu'un fourgon, par l'intermédiaire de deux articulations 11 permettant son pivotement autour d'un axe horizontal, perpendiculaire à la direction d'avancement du fourgon 4. Ce pivotement est commandé par deux vérins hydrauliques articulés 12, reliés par une extrémité au fourgon 4 et par l'extrémité opposée aux flancs 10b du plateau. Avantageusement, les articulations 11 peuvent être des paliers élastomères, dits communément « silent blocs », afin d'atténuer les vibrations et les chocs dus, par exemple, aux irrégularités de la chaussée.The pickup plate 10 is fixed to the front portion of a land motor vehicle 4, such as a van, by means of two hinges 11 allowing it to pivot about a horizontal axis, perpendicular to the direction of 4. This pivoting is controlled by two articulated hydraulic cylinders 12, connected at one end to the van 4 and the end opposite the sidewalls 10b of the tray. Advantageously, the joints 11 may be elastomeric bearings, so-called "silent blocks", in order to reduce vibrations and shocks due, for example, to unevenness of the roadway.

Comme le montrent les figures 1 et 4, lorsque les vérins 12 sont dans leur état rétracté, le plateau 10 est orienté verticalement et vient se positionner entre les phares 41 du véhicule 4, devant sa calandre 42. C'est la position non opérationnelle du dispositif ; on peut remarquer que le plateau 10, dans cette position, ne constitue pas un danger pour les autres véhicules.As shown by figures 1 and 4 when the cylinders 12 are in their retracted state, the plate 10 is oriented vertically and is positioned between the headlights 41 of the vehicle 4, in front of its shell 42. This is the non-operational position of the device; it can be noted that the plate 10, in this position, does not constitute a danger for other vehicles.

L'extension des vérins 12 amène le plateau 10 dans sa position abaissée de ramassage, dans laquelle le fond 10a s'étend parallèlement à la chaussée 3, à une hauteur par rapport à cette dernière comprise entre quelques millimètres et quelques centimètres. Un capteur 13, par exemple à ultrasons, et un système d'asservissement (non représenté) peuvent être prévus pour maintenir constante la distance entre le plateau 10 et la chaussée 3.The extension of the cylinders 12 brings the plate 10 into its lowered collection position, wherein the bottom 10a extends parallel to the roadway 3, at a height relative to the latter between a few millimeters and a few centimeters. A sensor 13, for example ultrasonic, and a servo system (not shown) may be provided to maintain constant the distance between the plate 10 and the roadway 3.

Une ou plusieurs roues « jockey » 14 - absentes dans le mode de réalisation des figures 3 à 7 - peuvent être prévues pour assurer l'absence de contact entre le fond 10a du plateau de ramassage et la chaussée 3, même lorsque ledit plateau est chargé d'objets ramassés.One or more "jockey" wheels 14 - absent in the embodiment of the Figures 3 to 7 - May be provided to ensure the absence of contact between the bottom 10a of the collection tray and the roadway 3, even when said tray is loaded with collected objects.

En variante, représentée en particulier sur la figure 4, le plateau de ramassage peut être monté de telle manière qu'en position abaissée une extrémité avant 19 de son fond, avantageusement en forme de lame et présentant une résistance mécanique suffisante, frotte sur la chaussée pour faciliter le ramassage d'objets par une action de raclage. Dans ce cas, la présence des roues 14 n'est généralement pas nécessaire.Alternatively, shown in particular on the figure 4 , the pickup tray can be mounted such that in the lowered position a front end 19 of its bottom, preferably blade-shaped and having sufficient strength, rubs on the floor to facilitate the pickup of objects by an action scraping. In this case, the presence of the wheels 14 is generally not necessary.

Dans l'exemple de la figure 4, l'ensemble barre 161/tiges 160 est située en avant par rapport à la lame de raclage 19 pour empêcher toute projection vers le haut d'objets gisant sur la chaussée.In the example of the figure 4 , the bar 161 / rod 160 assembly is located forwardly relative to the scraper blade 19 to prevent any upward projection of objects lying on the roadway.

Comme illustré sur les figures 5 et 7, des bavettes 15 peuvent être prévues à l'avant du plateau 10 afin de former un entonnoir pour diriger vers le dispositif de ramassage des objets situés sur les côtés. Avantageusement, ces bavettes peuvent être pivotantes et se replier le long de flancs 10b ou devant l'ouverture avant du plateau lorsque ce dernier se trouve en position non opérationnelle (relevée). Le pivotement des bavettes 15 peut être commandé par des moteurs électriques. Plus avantageusement, des moyens élastiques peuvent être prévus pour faire pivoter les bavettes 15 vers leur position dépliée lorsque le plateau s'abaisse ; en position relevée, la force de pesanteur surmonte la force de rappel élastique et ramène lesdites bavettes dans leur position fermée.As illustrated on figures 5 and 7 , bibs 15 may be provided at the front of the tray 10 to form a funnel for directing to the collection device objects on the sides. Advantageously, these flaps can be pivoted and fold along the sidewalls 10b or in front of the front opening of the plate when the latter is in the nonoperational (raised) position. The pivoting of the flaps 15 can be controlled by electric motors. More preferably, resilient means may be provided for pivoting the flaps 15 to their unfolded position as the tray lowers; in the raised position, the Gravity force overcomes the elastic restoring force and returns said bibs to their closed position.

Selon une variante avantageuse de l'invention, des moyens d'actionnement non représentés sur les figures peuvent être prévus afin de permettre le pivotement et/ou la translation du plateau de ramassage 10 vers la droite ou vers la gauche, lorsque ce dernier se trouve dans sa position abaissée. Cela permet audit plateau de pousser un objet trop lourd ou trop grand pour être ramassé vers un côté de la chaussée, à la manière d'un chasse-neige.According to an advantageous variant of the invention, actuating means not shown in the figures can be provided to allow the pivoting and / or the translation of the pickup plate 10 to the right or to the left, when the latter is located in its lowered position. This allows the tray to push an object too heavy or too large to be picked up to one side of the road, like a snow plow.

Des moyens de commande des différents actionneurs du dispositif 1 (vérins 12, moteur électrique du rouleau-brosse 16, actionneurs des bavettes 15, etc.) sont prévus à l'intérieur du fourgon 4, dans une position accessible au conducteur et/ou au passager.Control means of the various actuators of the device 1 (cylinders 12, electric motor of the brush roller 16, actuators of the flaps 15, etc.) are provided inside the van 4, in a position accessible to the driver and / or the passenger.

Pour des raisons de sécurité, le fourgon 4 est de préférence équipé de dispositifs lumineux de signalisation tels que des flèches, un panneau à message variable, un gyrophare.For safety reasons, the van 4 is preferably equipped with signaling light devices such as arrows, a variable message sign, a beacon.

Le dispositif de l'invention a été décrit en association avec un véhicule de type fourgon ; cependant, il ne s'agit nullement d'une limitation. En effet, un tel dispositif pourrait être monté sur un véhicule plus léger, tel qu'une voiture ou, au contraire, sur un poids-lourd.The device of the invention has been described in association with a van-type vehicle; however, it is by no means a limitation. Indeed, such a device could be mounted on a lighter vehicle, such as a car or, conversely, on a truck.

Le plateau de ramassage représenté sur les figures présente une largeur inférieure à celle du véhicule, de manière à ne pas couvrir les feux de ce dernier lorsqu'il se trouve dans sa position relevée. Là encore, cette limitation n'a rien d'essentiel, et le plateau pourrait présenter une largeur égale, voire supérieure, à celle du véhicule. Dans ce cas, les bavettes 15 peuvent être omises.The pickup plate shown in the figures has a width less than that of the vehicle, so as not to cover the lights of the latter when it is in its raised position. Again, this limitation is not essential, and the tray could have a width equal to or greater than that of the vehicle. In this case, the flaps 15 may be omitted.

Des essais ont été réalisés et on permis de montrer que le dispositif de l'invention permet de ramasser avec une très grande fiabilité des objets de dimensions importantes, tels que des pots d'échappement de camions, et cela à une vitesse de 50 - 60 km/h.Tests have been carried out and it has been shown that the device of the invention makes it possible to pick up with very high reliability objects of large dimensions, such as truck exhausts, and this at a speed of 50 - 60 km / h.
