Description

La présente invention concerne les dispositifs de nettoyage du sol et plus particulièrement les dispositifs de nettoyage du sol destinés au nettoyage des trottoirs. Parmi les souillures qui salissent les trottoirs, les déjections canines causent parfois des problèmes en ce qui concerne le nettoyage du trottoir. En effet, on a déjà conçu des appareils destinés à prélever les immondices, mais il est parfois difficile de supprimer toutes les traces sur le trottoir. Or ces traces constituent un désagrément notable, et il est parfois difficile de supprimer toutes les traces sur le trottoir. Il est nécessaire de pouvoir les supprimer totalement dans tous les cas, lorsque l'on prélevé les déjections canines.The present invention relates to floor cleaning devices and more particularly to floor cleaning devices intended for cleaning sidewalks. Among the stains that soil the sidewalks, dog excrement can sometimes cause problems when it comes to cleaning the sidewalk. Indeed, we have already designed devices to collect litter, but it is sometimes difficult to remove all traces on the sidewalk. However, these traces constitute a significant inconvenience, and it is sometimes difficult to remove all the traces on the sidewalk. It is necessary to be able to completely remove them in all cases, when we collect dog excrement.

Par ailleurs, dans le cas de sols meubles tels que du stable, il est souhaitable de ne pas détériorer le sol lors du prélèvement tout en réalisant un nettoyage impeccable.Furthermore, in the case of loose floors such as stable, it is desirable not to deteriorate the floor during removal while performing impeccable cleaning.

La présente invention a donc pour objet un dispositif de nettoyage du sol destiné plus particulièrement au prélèvement de déjections canines qui permet d'obtenir un nettoyage impeccable quel que soit l'état des déjections canines et quel que soit l'état du sol.The present invention therefore relates to a floor cleaning device intended more particularly for the collection of dog excrement which makes it possible to obtain impeccable cleaning whatever the state of the dog excrement and whatever the state of the ground.

Le dispositif selon la présente invention est notamment remarquable en ce qu'il comporte en combinaison :

  • - une cloche d'aspiration mobile entre deux positions, l'une opérationnelle où elle est en retrait par rapport au sol, ladite cloche renfermant au moins une buse d'aspersion reliée à une source d'agent de nettoyage sous pression, et
  • - un conduit d'aspiration relié à une enceinte à dépression, elle-même raccordée à un réservoir de stockage des eaux usées, l'axe du conduit d'aspiration des eaux usées étant dans un plan sensiblement parallèle au sol et le plus proche de ce dernier, et le jet de la buse étant monté mobile autour d'un axe horizontal pour converger en direction du flux d'aspiration des eaux usées.
The device according to the present invention is notably remarkable in that it comprises in combination:
  • a suction bell movable between two positions, one operational where it is set back from the ground, said bell containing at least one spray nozzle connected to a source of pressurized cleaning agent, and
  • - a suction pipe connected to a vacuum enclosure, itself connected to a waste water storage tank, the axis of the waste water suction pipe being in a plane substantially parallel to the ground and closest to the latter, and the jet of the nozzle being mounted movable about a horizontal axis to converge in the direction of the suction flow used waters.

Le jet à haute pression obtenu grâce à la buse précitée permet de réaliser un nettoyage complet du sol en éliminant toute trace de la souillure; en position fonctionnelle, la cloche est en contact avec le sol et on obtient une enceinte étanche reliée au conduit d'aspiration qui aspire les eaux usées constituées par le mélange de l'agent de nettoyage et les fragments de la souillure à prélever. L'utilisation d'un jet à haute pression per met en particulier de fragmenter la souillure à prélever, ce qui facilite ensuite son évacuation. La disposition tangentielle par rapport au sol du conduit d'aspiration permet une récupération parfaite des eaux usées; par ailleurs, la rotation du jet en direction du conduit d'aspiration permet d'une part d'améliorer l'effet de fragmentation de la déjection à prélever et d'autre part d'améliorer l'effet d'expulsion des fragments obtenus.The high pressure jet obtained thanks to the aforementioned nozzle makes it possible to carry out a complete cleaning of the ground by eliminating any trace of the stain; in the functional position, the bell is in contact with the ground and a sealed enclosure is obtained connected to the suction pipe which sucks the waste water constituted by the mixture of the cleaning agent and the fragments of the soil to be sampled. The use of a high pressure jet allows in particular to fragment the soil to be sampled, which then facilitates its evacuation. The tangential arrangement relative to the ground of the suction pipe allows perfect recovery of wastewater; moreover, the rotation of the jet in the direction of the suction duct makes it possible on the one hand to improve the fragmentation effect of the dejection to be sampled and on the other hand to improve the expulsion effect of the fragments obtained.

Selon encore une autre caractéristique de l'invention, la cloche comprend d'une part, au moins un premier orifice de prise d'air extérieur situé sensiblement dans l'axe du flux d'aspiration des eaux usées, et d'autre part, au moins un deuxième orifice de prise d'air extérieur aménagé dans sa surface supérieure et sensiblement perpendiculaire au premier orifice précité. La présence des orifices de prise d'air permet d'éviter un effet de ventouse; par ailleurs, leur disposition sur la cloche permet d'améliorer le mouvement d'expulsion des souillures à prélever.According to yet another characteristic of the invention, the bell comprises on the one hand, at least a first outside air intake orifice situated substantially in the axis of the suction flow of the wastewater, and on the other hand, at least one second orifice for the outside air intake arranged in its upper surface and substantially perpendicular to the aforementioned first orifice. The presence of the air intake orifices makes it possible to avoid a suction cup effect; in addition, their arrangement on the bell makes it possible to improve the movement of expulsion of the stains to be sampled.

Selon encore une autre caractéristique de l'invention, la cloche comporte une deuxième buse disposée dans le plan du flux des eaux usées de manière à réaliser un balayage horizontal. Cette buse disposée tangentiellement par rapport au sol et dont le jet est dirigé vers le conduit d'aspiration, permet de prélever des souillures sur un sol meuble tel que du sable sans le détériorer.According to yet another characteristic of the invention, the bell comprises a second nozzle arranged in the plane of the flow of wastewater so as to carry out a horizontal sweep. This nozzle disposed tangentially with respect to the ground and the jet of which is directed towards the suction duct, makes it possible to remove soil from loose soil such as sand without damaging it.

Selon encore une autre caractéristique de l'invention, la buse d'aspersion est montée sur un bras articulé dirigé vers le conduit d'aspiration des eaux usées, l'axe de la buse étant déporté vers ledit conduit par rapport à l'axe d'articulation dudit bras et l'on prévoit un dispositif de rappel de la buse vers sa position de repos dans laquelle le jet de la buse est incliné vers le conduit d'aspiration par rapport à la verticale.According to yet another characteristic of the invention, the spray nozzle is mounted on an articulated arm directed towards the wastewater suction pipe, the axis of the nozzle being offset towards said conduit relative to the axis of articulation of said arm and there is provided a device for returning the nozzle to its rest position in which the jet of the nozzle is inclined towards the suction conduit relative to the vertical.

Comme on peut le voir sur les figs. et 2, le dispositif de nettoyage du sol conforme à la présente invention est essentiellement constitué d'une cloche d'aspiration 1 qui présente par exemple, vue en plan, la forme d'une raquette; cette cloche d'aspiration est mobile entre deux positions, à savoir une position fonctionnelle de travail dans laquelle elle repose sur le sol et une position de repos où elle se trouve en retrait par rapport au sol. On voit sur la fig. 3 en particulier la position de travail représentée en trait mixte et la position de repos représentée en trait continu. Cette cloche comporte un conduit d'aspiration disposé tangentiellement au sol 3 et le plus près possible de ce dernier. Ce conduit 2 est disposé à l'extrémité à la partie convergente 5 de la cloche 1. Une première buse d'aspersion 6 est disposée dans la partie supérieure de la cloche 1 à son extrémité 7 opposée à la partie convergente 5. Cette buse est montée à rotation autour d'un axe horizontal 8 qui est sensiblement perpendiculaire à la direction d'aspiration des eaux usées par le conduit 2, c'est-à-dire perpendiculairement à l'axe de symétrie 9 de la cloche 1.As can be seen in figs. and 2, the floor cleaning device according to the present invention essentially consists of a suction bell 1 which has, for example, in plan view, the shape of a racket; this suction bell is movable between two positions, know a functional working position in which it rests on the ground and a rest position where it is set back from the ground. We see in fig. 3 in particular the working position shown in phantom and the rest position shown in solid line. This bell comprises a suction duct arranged tangentially to the ground 3 and as close as possible to the latter. This duct 2 is arranged at the end at the converging part 5 of the bell 1. A first spray nozzle 6 is arranged in the upper part of the bell 1 at its end 7 opposite to the converging part 5. This nozzle is rotatably mounted around a horizontal axis 8 which is substantially perpendicular to the direction of suction of the wastewater through the conduit 2, that is to say perpendicular to the axis of symmetry 9 of the bell 1.

La cloche comprend au moins un premier orifice de prise d'air extérieur 11 aménagé dans l'extrémité 7 de la buse 1 et qui est disposé sensiblement dans l'axe du flux d'aspiration des eaux usées, c'est-à-dire parallèlement à l'axe 9 de symétrie de la cloche et au moins un deuxième orifice de prise d'air extérieur 12 qui est aménagé dans la surface supérieure 13 de la cloche 1 et qui est sensiblement perpendiculaire au premier orifice 11.The bell comprises at least a first external air intake orifice 11 arranged in the end 7 of the nozzle 1 and which is disposed substantially in the axis of the suction flow of the wastewater, that is to say parallel to the axis 9 of symmetry of the bell and at least one second external air intake orifice 12 which is arranged in the upper surface 13 of the bell 1 and which is substantially perpendicular to the first orifice 11.

Avantageusement, on prévoit une deuxième buse de balayage horizontal 14 qui est disposée dans l'extrémité 7 opposée au conduit 2 de la cloche 1. Cette buse se trouve donc dans le plan d'aspiration des eaux usées et son jet est sensiblement horizontal de manière à réaliser un balayage horizontal de la déjection à prélever, ce balayage horizontal limitant au maximum la détérioration du sol dans le cas du sol meuble tout en permettant d'obtenir un nettoyage correct.Advantageously, a second horizontal scanning nozzle 14 is provided which is disposed in the end 7 opposite to the duct 2 of the bell 1. This nozzle is therefore located in the wastewater suction plane and its jet is substantially horizontal so to carry out a horizontal scan of the dejection to be sampled, this horizontal scan minimizing the deterioration of the soil in the case of loose soil while allowing correct cleaning to be obtained.

La cloche d'aspiration 1 comporte un joint annulaire 15 sur son bord inférieur; ce joint est du type à écrasement et il permet d'obtenir une bonne étanchéité de la cloche sur le sol, même si ce dernier n'est pas absolument plat.The suction bell 1 has an annular seal 15 on its lower edge; this seal is of the crushing type and it makes it possible to obtain a good seal of the bell on the ground, even if the latter is not absolutely flat.

La cloche d'aspiration qui vient d'être décrite est reliée d'une part, par son conduit 2, à une unité d'aspiration qui comporte un filtre, un compresseur et un réservoir des eaux usées et d'autre part à une source d'agent de nettoyage comprenant un réservoir et une pompe à haute pression qui débite le liquide de nettoyage contenu dans le réservoir dans les buses 6 et 14.The suction bell which has just been described is connected on the one hand, by its conduit 2, to a suction unit which comprises a filter, a compressor and a waste water tank and on the other hand to a source of cleaning agent comprising a tank and a pump at high pressure which delivers the cleaning liquid contained in the tank into the nozzles 6 and 14.

Le dispositif de nettoyage du sol conforme à la présente invention est monté sur un engin mobile susceptible de se déplacer sur un trottoir ; cet engin mobile est avantageusement constitué par une moto comme cela est représenté aux fig.3 et 4 où l'on voit une moto 16 de type connu qui a été modifiée pour recevoir le dispositif de nettoyage du sol sel'on l'invention.The floor cleaning device according to the present invention is mounted on a mobile machine capable of moving on a sidewalk; this mobile machine is advantageously constituted by a motorcycle as shown in fig.3 and 4 where we see a motorcycle 16 of known type which has been modified to receive the floor cleaning device according to the invention.

Comme on peut le voir sur la fig.4, le dispositif de nettoyage selon l'invention est disposé sur le côté de la moto 16 qui peut être équipée d'un ou de deux dispositifs disposés de part et d'autre de la moto.As can be seen in fig.4, the cleaning device according to the invention is arranged on the side of the motorcycle 16 which can be equipped with one or two devices arranged on either side of the motorcycle.

Comme on peut le voir sur les fig.3 et 4, la cloche 1 est montée sur un support 17 qui est fixé sur la moto 16 au voisinage du repose-pied à articulation autour d'un axe horizontal 18 ; ce support comporte essentiellement une barre contre-coudée 19 qui estprolongée sur le côté de la moto à son extrémité opposée à l'axe 18 par un support tubulaire horizontal 21 dans lequel un arbre 22 est fixé à rotation. L'extrémité de cet arbre 22 porte un cadre 23 sur lequel la cloche 1 est fixée à rotation autour d'un axe 24 horizontal parallèle à l'axe de la moto et à l'axe de symétrie 9 de ladite cloche. Le cadre 23 est constitué d'une pièce en forme de U aux extrémités desquelles sont fixées à rotation deux pattes 25 et 26 fixées sur la surface supérieure 13 de la cloche 1 par le plan de son axe de symétrie 9.As can be seen in fig.3 and 4, the bell 1 is mounted on a support 17 which is fixed on the motorcycle 16 in the vicinity of the footrest articulated around a horizontal axis 18; this support essentially comprises a bent bar 19 which is extended on the side of the motorcycle at its end opposite the axis 18 by a horizontal tubular support 21 in which a shaft 22 is fixed for rotation. The end of this shaft 22 carries a frame 23 on which the bell 1 is fixed for rotation about a horizontal axis 24 parallel to the axis of the motorcycle and to the axis of symmetry 9 of said bell. The frame 23 consists of a U-shaped piece at the ends of which two legs 25 and 26 are fixed to rotation fixed on the upper surface 13 of the bell 1 by the plane of its axis of symmetry 9.

Conformément à l'invention, l'ensemble de l'unité d'aspiration, de la source de liquide de nettoyage et de la pompe à haute pression est disposé à l'arrière de la moto au niveau du siège passager. Sur les fig.3 et 4, on voit en 27 la turbine d'aspiration qui crée une aspiration dans un filtre 28 qui est relié au conduit d'aspiration 2 de la cloche par une conduite 29 ; l'unité d'aspiration est complétée par un réservoir d'eaux usées 31 qui présente la forme d'un U de manière à entourer la roue arrière 32 de la moto.According to the invention, the assembly of the suction unit, the source of cleaning liquid and the high-pressure pump is arranged at the rear of the motorcycle at the passenger seat. On fig. 3 and 4, we see in 27 the suction turbine which creates suction in a filter 28 which is connected to the suction pipe 2 of the bell by a pipe 29; the suction unit is completed by a waste water tank 31 which has the shape of a U so as to surround the rear wheel 32 of the motorcycle.

Avantageusement, le réservoir des eaux usées 11 comporte un tuyau flexible 33 raccordé à la partie inférieure du réservoir 31 et fermé à son extrémité libre par un dispositif de fermeture rapide. En position de travail ce tuyau de vidange 33 est fixé le long du réservoir 31.Advantageously, the waste water tank 11 comprises a flexible pipe 33 connected to the lower part of the tank 31 and closed at its free end by a quick closing device. In the working position this drain pipe 33 is fixed along the tank 31.

Le dispositif d'alimentation en agent nettoyant est constitué par un réservoir 34 contenant un agent de nettoyage qui peut être simplement constitué par de l'eau propre. Avantageusement ce réservoir comporte deux parties symétriques 35 et 36 disposées de part et d'autre de la roue arrière 32. L'eau contenue dans ce réservoir double est mise sous pression par un compresseur 37 tel qu'une pompe à haute pression et l'eau sous pression est amenée aux buses 4 et 14 par l'intermédiaire de conduites souples, non représentées. Un robinet inverseur 38 permet de sélectionner l'une des deux buses 4 ou 14 ; ce robinet peut éventuellement comporter une position neutre permettant un fonctionnement sans aspersion d'agent de nettoyage dans le cas de déjections très sèches et n'adhérant pas au trottoir.The cleaning agent supply device consists of a reservoir 34 containing a cleaning agent which may simply consist of clean water. Advantageously, this tank has two symmetrical parts 35 and 36 arranged on either side of the rear wheel 32. The water contained in this double tank is pressurized by a compressor 37 such as a high pressure pump and the pressurized water is supplied to nozzles 4 and 14 via flexible pipes, not shown. A reversing tap 38 makes it possible to select one of the two nozzles 4 or 14; this tap may possibly have a neutral position allowing operation without spraying cleaning agent in the case of very dry excrement and not adhering to the sidewalk.

Comme on peut le voir en particulier sur la fig. 4, l'ensemble fonctionnel comprenant l'unité d'aspiration et la source d'agent de nettoyage sous pression qui sont par exemple entrainés par un moteur thermique 39 est disposé à l'arrière de la moto de manière à ne pas dépasser du gabarit normal de la moto, c'est-à-dire que l'ensemble de la largeur correspond à la largeur du guidon de la moto. On peut voir également sur cette figure, que en position normale comme représenté en trait plein, la cloche d'aspiration 1 reste également dans les limites du gabarit de la moto, c'est-à-dire qu'elle ne dépasse pas en largeur du guidon de la moto. Toutefois, dans le cas où l'on désire intervenir le long de murs, par exemple ou autour d'arbres, il peut être désirable de faire dépasser la tête de nettoyage 1 du gabarit de la moto comme cela est représenté en trait mixte sur la fig.4. Cela est avantageusement obtenu par le fait que l'arbre 22 peut être déplacé en translation dans le support tubulaire 21 de manière à prendre plusieurs positions déterminées dans ce support ; l'arbre 22 est alors verrouillé dans chacune de ces positions au moyen du dispositif de verrouillage tel que schématisé en 41 sur la fig.2.As can be seen in particular in FIG. 4, the functional assembly comprising the suction unit and the source of pressurized cleaning agent which are for example driven by a heat engine 39 is arranged at the rear of the motorcycle so as not to exceed the template normal of the motorcycle, that is to say that the entire width corresponds to the width of the handlebars of the motorcycle. We can also see in this figure, that in normal position as shown in solid lines, the suction bell 1 also remains within the limits of the size of the motorcycle, that is to say that it does not exceed in width. the handlebars of the motorcycle. However, in the case where one wishes to intervene along walls, for example or around trees, it may be desirable to extend the cleaning head 1 of the size of the motorcycle as shown in phantom in fig.4. This is advantageously obtained by the fact that the shaft 22 can be moved in translation in the tubular support 21 so as to take several determined positions in this support; the shaft 22 is then locked in each of these positions by means of the locking device as shown diagrammatically at 41 in FIG. 2.

Comme on peut le voir en particulier sur la fig.3 la tête de nettoyage est fixée sur la moto à articulation dans un plan vertical parallèle à la moto de telle manière que la position de repos représentée en trait plein sur cette figure, soit sensiblement alignée avec la position de travail représentée en trait mixte. Le passage de la position de repos à la position de travail est obtenu au moyen d'un levier de manoeuvre 42 solidaire du support 17 et qui est verrouillé dans la position de repos.As can be seen in particular in fig.3 the cleaning head is fixed to the articulated motorcycle in a vertical plane parallel to the motorcycle so that the rest position shown in solid lines in this figure, is substantially aligned with the working position shown in phantom. The passage from the rest position to the working position is obtained by means of an operating lever 42 secured to the support 17 and which is locked in the rest position.

Selon une caractéristique de l'invention, ce levier 42 commande la manette d'accélérateur ou manette des gaz du moteur thermique 39 de telle manière qu'en position de repos ce dernier tourne au ralenti et qu'il tourne à vitesse élevée lorsque la tête de nettoyage 1 vient dans la position de travail.According to a characteristic of the invention, this lever 42 controls the throttle or throttle lever of the heat engine 39 so that in the rest position the latter idles and that it rotates at high speed when the head cleaning 1 comes into the working position.

Les fig.5 et 6 illustrent ce mode de réalisation. La fig.5 est une vue en coupe partielle du levier 42 et la fig.6 est une vue en coupe suivant la ligne VI-VI de la fig.5. Le levier est constitué d'une partie plate 43 qui est fixée à son extrémité inférieure sur le support 17 et qui est prolongée vers le haut par une partie cylindrique 44 creuse dans laquelle coulisse un arbre 45 terminé par une poignée 46.Figs 5 and 6 illustrate this embodiment. Fig.5 is a partial sectional view of the lever 42 and Fig.6 is a sectional view along line VI-VI of Fig.5. The lever consists of a flat part 43 which is fixed at its lower end to the support 17 and which is extended upwards by a hollow cylindrical part 44 in which slides a shaft 45 terminated by a handle 46.

Une pièce de liaison 47 est fixée sur la partie inférieure 43 du levier et son extrémité libre est reliée à l'extrémité d'un câble de commande des gaz du moteur 39.A connecting piece 47 is fixed on the lower part 43 of the lever and its free end is connected to the end of a cable for controlling the gases from the engine 39.

La partie plate 43 du levier s'engage dans une fourche 48 fixée à la moto et dontl'extrémité libre présente un chanfrein 49 dirigé vers le bas et vers l'avant par rapport à la moto. Une pièce de verrouillage constituée par une noix 51 est fixée à l'extrémité inférieure de l'arbre 45 de manière à pouvoir coulisser dans la partie plate 43 sur une certaine .course ; ceci est obtenu grâce à une lumière 52 aménagée dans la noix 51 et dans laquelle coulisse un axe 53 solidaire de la partie plate 43. L'ensemble de l'arbre 45 et de la noix 53 est maintenu en position basse au moyen d'un ressort 54 travaillant en compression. En position de verrouillage dans laquelle le levier est disposé verticalement, la noix 51 s'engage dans deux évidements 55 aménagés dans les deux parois de la fourche 48. Le fonctionnement de ce dispositif de verrouillage est le suivant : lorsque l'on veut déverrouiller, il suffit de lever l'ensemble de l'arbre 45 et de la noix 51 pour les dégager des encoches 55, l'ensemble de nettoyage descend alors de son propre poids et vient en contact avec le sol, le levier venant alors dans la position représentée à gauche de la fig.5. Lorsque l'on relève le levier, la noix 51 glisse sur le chanfrein 49 et vient ensuite se verrouiller dans les encoches 55 sous l'action du ressort 54. Le verrouillage est donc automatique lorsque l'on revient à la position de repos.The flat part 43 of the lever engages in a fork 48 fixed to the motorcycle and the free end of which has a chamfer 49 directed downward and forward with respect to the motorcycle. A locking piece constituted by a nut 51 is fixed to the lower end of the shaft 45 so as to be able to slide in the flat part 43 over a certain distance; this is obtained thanks to a light 52 arranged in the nut 51 and in which slides an axis 53 integral with the flat part 43. The assembly of the shaft 45 and the nut 53 is kept in the low position by means of a spring 54 working in compression. In the locking position in which the lever is arranged vertically, the nut 51 engages in two recesses 55 arranged in the two walls of the fork 48. The operation of this locking device is as follows: when it is desired to unlock, it suffices to lift the assembly of the shaft 45 and the nut 51 to release them from the notches 55, the cleaning assembly then descends from its own weight and comes into contact with the ground, the lever then coming into the position represented on the left of fig. 5. When the lever is raised, the nut 51 slides on the chamfer 49 and then locks in the notches 55 under the action of the spring 54. The locking is therefore automatic when one returns to the rest position.

Avantageusement, le levier 42 commande également l'admission du liquide de nettoyage à haute pression dans les buses 4 et 14. Par ailleurs, la rotation de la buse d'aspersion 4 en direction du conduit d'aspiration 2 est obtenue de manière automatique sous l'action de la pression de l'eau envoyée à la buse.Advantageously, the lever 42 also controls the admission of the high-pressure cleaning liquid into the nozzles 4 and 14. Furthermore, the rotation of the spray nozzle 4 in the direction of the suction duct 2 is obtained automatically under the action of the pressure of the water sent to the nozzle.

Le fonctionnement du dispositif de nettoyage du sol qui vient d'être décrit est le suivant. En position de repos, le dispositif de nettoyage est dans la position représentée en trait plein sur les fig.3 et 4 et l'on constate que cette disposition permet de conserver la moto dans son état normal en ce qui concerne par exemple la garde au sol, l'accès aux pédales, le rayon de braquage. Comme cela a été indiqué plus haut, l'encombrement de la moto et en particulier de l'ensemble de puissance disposé à l'arrière est limité à l'encombrement du guidon si bien que la présence de cet ensemble de puissance ne modifie pas du tout la possibilité d'évolution de la moto. Lorsque l'opérateur désire prélever une déjection sur un trottoir, il vient à hauteur de cette dernière, la précision du positionnement étant facilitée par le fait que les positions de repos et de travail de la tête de nettoyage 1 sont sensiblement alignés. L'opérateur doit tout d'abord sélectionner le mode de fonctionnement de la tête de nettoyage qui pefit fonctionner soit avec la buse d'aspersion 4 à jet rotatifs soit avec la buse de balayage horizontal 14 soit éventuellement pour des déjections très sèches et n'accrochant pas sans action d'aucune des buses ; ce choix est réalisé au moyen du robinet inverseur 38. Il ne reste plus à l'opérateur qu'à déverrouiller le levier 42 et laisser descendre la tête de nettoyage sur la déjection. Comme cela a été indiqué plus haut, le déplacement du levier entraine de manière automatique le passage du régime ralenti au régime accéléré pour le moteur d'entrainement 39, et l'alimentation des buses en agent de nettoyage à haute pression. Du fait de la suspension selon deux axes horizontaux perpendiculaires de la tête d'aspiration sur le support 17, et grâce au joint 15,la tête d'aspiration 1 s'adapte parfaitement au sol, l'écrasement de ce joint assurant l'élan- chéité.The operation of the floor cleaning device which has just been described is as follows. In the rest position, the cleaning device is in the position shown in solid lines in FIGS. 3 and 4 and it can be seen that this arrangement makes it possible to keep the motorcycle in its normal state as regards for example the guard at ground, access to pedals, turning radius. As stated more top, the size of the motorcycle and in particular of the power assembly arranged at the rear is limited to the size of the handlebars so that the presence of this power assembly does not at all modify the possibility of evolution of motorcycle. When the operator wishes to take an ejection from a sidewalk, he comes up to the latter, the positioning accuracy being facilitated by the fact that the rest and working positions of the cleaning head 1 are substantially aligned. The operator must first select the operating mode of the cleaning head which can operate either with the spray nozzle 4 with rotary jet or with the horizontal scanning nozzle 14 or possibly for very dry droppings and does not not hanging without action of any of the nozzles; this choice is made by means of the reversing tap 38. It only remains for the operator to unlock the lever 42 and let the cleaning head descend on the dejection. As indicated above, the movement of the lever automatically causes the transition from the idle speed to the accelerated speed for the drive motor 39, and the supply of the nozzles with high-pressure cleaning agent. Due to the suspension along two perpendicular horizontal axes of the suction head on the support 17, and thanks to the seal 15, the suction head 1 adapts perfectly to the ground, the crushing of this seal ensuring the momentum - cheerfulness.

Du fait de sa grande efficacité due en particulier à l'action de la buse à jet rotatif, l'opération est très courte, (de l'ordre de quelques secondes) et l'opérateur peut alors relever la tête pour faire avancer la moto et procéder à d'autres prélèvements.Due to its high efficiency due in particular to the action of the rotary jet nozzle, the operation is very short, (on the order of a few seconds) and the operator can then raise his head to move the motorcycle forward. and take other samples s .

Comme indiqué précédemment, dans le cas où le sol est meuble, en particulier dans le cas de sable, on utilise 1a buse 14 de balayage horizontal pour éviter toute dégradation notable du sol.As indicated previously, in the case where the soil is loose, in particular in the case of sand, the horizontal scanning nozzle 14 is used to avoid any significant degradation of the soil.

Lorsque le réservoir d'eaux usées est plein, l'opérateur ouvre le tuyau de vidange 33 et le décroche du réser- voir 31 pour le mettre dans une bouche d'égout ; cela permet d'obtenir une vidange rapide sans avoir à retourner à l'endroit où est normalement remisée la moto. De même, il est possible de refaire le plein du réservoir 34 en se branchant sur les bornes de distribution d'eau se trouvant dans les trottoirs.When the waste water tank is full, the operator opens the drain pipe 33 and unhooks it from the tank - see 31 to put it in a manhole; this allows rapid emptying without having to return to the place where the motorcycle is normally stored. Similarly, it is possible to replenish the tank 34 by connecting to the water distribution terminals located in the sidewalks.

La possiblité de décaler la tête de nettoyage vers l'extérieur de la moto, comme représenté en trait mixte sur la fig.4, permet de pouvoir travailler même dans des endroits difficilement accessibles tels que le long des murs ou autour des arbres. La fixation de l'arbre 22 dans le support tubulaire 21 permet un démontage rapide de la tête de nettoyage 1 et on obtient alors une moto tout à fait normale, ce qui permet d'effectuer facilement de longs déplacements avant·d'arriver sur le lieu de travail. La fixation du bloc de puissance à l'arrière de la moto est également faite de manière facilement amovible, de manière à pouvoir retrouver une moto normale et à faciliter l'entretien et la maintenance du dispositif de nettoyage du sol selon la présente invention.The possibility of shifting the cleaning head towards the outside of the motorcycle, as shown in phantom in Fig. 4, makes it possible to be able to work even in places that are difficult to access such as along the walls or around the trees. The fixing of the shaft 22 in the tubular support 21 allows rapid disassembly of the cleaning head 1 and one then obtains a completely normal motorcycle, which makes it possible to easily make long trips before · arriving on the workplace. The attachment of the power unit to the rear of the motorcycle is also made in an easily removable manner, so as to be able to find a normal motorcycle and to facilitate the upkeep and maintenance of the floor cleaning device according to the present invention.

De manière avantageuse, la surface supérieure 13 de la tête d'aspiration 1 est réalisée en un matériau translucide, ce qui permet de surveiller le fonctionnement du dispositif.Advantageously, the upper surface 13 of the suction head 1 is made of a translucent material, which makes it possible to monitor the operation of the device.

Sur les figures 7 à 13, les éléments semblables à ceux des figures 1 à 6 portent les mêmes références.In Figures 7 to 13, elements similar to those in Figures 1 to 6 have the same references.

Sur les figures 7 et 8, la buse d'aspersion 4 est portée par un bras 61 mobile en rotation autour de l'axe 8; ce bras s'étend vers l'avant de la cloche, c'est-à-dire en direction du conduit d'aspiration 2; la buse d'aspersion 4 est orientée de telle manière que, dans sa position de repos qui est représentée sur la figure 7, l'axe 62 du jet de la buse se trouve légèrement incliné vers l'avant par rapport à la verticale 63. De cette manière lorsque l'on envoie du liquide de nettoyage sous pression dans la buse 4, le jet de-cette dernière frappe le sol 3 en oblique, ce qui entraine la déviation vers l'avant du jet de la buse et par suite la rotation du bras 61 dans le sens-inverse des aiguilles d'une montre jusqu'à ce que la buse arrive dans la position extrême où l'axe de son jet se trouve dans la position présentée en 62', position dans laquelle l'impact du jet est proche du conduit d'aspiration 2.In FIGS. 7 and 8, the spray nozzle 4 is carried by an arm 61 movable in rotation about the axis 8; this arm extends towards the front of the bell, that is to say in the direction of the suction duct 2; the spray nozzle 4 is oriented in such a way that, in its rest position which is shown in FIG. 7, the axis 62 of the jet of the nozzle is slightly inclined towards the front relative to the vertical 63. In this way when sending cleaning liquid under pressure into the nozzle 4, the jet of the latter strikes the ground 3 obliquely, which causes the deflection of the jet of the nozzle towards the front and consequently the rotation of arm 61 anti-clockwise until the nozzle arrives in the extreme position where the axis of its jet is in the position presented at 62 ′, position in which the impact of the jet is close to the suction duct 2.

La buse d'aspersion 4 est rappelée dans sa position de repos représentée sur la figure 7 par un dispositif de rappel schématisé par le ressort 64; de cette manière lorsque l'on interrompt l'alimentation de la buse,son jet cesse et elle revient dans sa position de repos représentée à la figure 7. Avantageusement, le dispositif de rappel est constitué par le conduit d'alimentation de la buse qui est alors réalisé en une matière flexible.The spray nozzle 4 is returned to its rest position shown in Figure 7 by a return device shown schematically by the spring 64; in this way when the supply to the nozzle is interrupted, its jet ceases and it returns to its rest position shown in FIG. 7 . Advantageously, the return device is constituted by the nozzle supply duct which is then made of a flexible material.

Selon une caractéristique de l'invention, l'alimentation de la buse d'aspersion 14 est commandée par un organe manuel de commande non représenté monostable du type bouton poussoir de manière à permettre l'envoi d'impulsions de liquide dans la buse.According to a characteristic of the invention, the supply of the spray nozzle 14 is controlled by a manual control member, not shown, monostable of the push button type so as to allow pulses of liquid to be sent into the nozzle.

Grâce à ces dispositiorz, chaque impulsion d'agent de nettoyage entraîne un mouvement de balayage du jet de la buse vers le conduit d'aspiration 2. On n'utilise alors que la quantité de liquide nécessaire pour le décollement de la souillure à prélever. Le fonctionnement du dispositif de nettoyage selon l'invention est facilement contrôle par le fait que la face supérieure 13 de la cloche 1 est transparente. De ce fait, l'opérateur n'envoie que le nombre d'impulsions nécessaires à un nettoyage efficace du sol 3; il en résulte donc une économie notable de l'agent de nettoyage et par suite une plus grande autonomie du dispositif selon l'invention, ce qui est particulièrement important lorsqu'il est porté par une moto.Thanks to these devices, each pulse of cleaning agent causes a sweeping movement of the jet from the nozzle towards the suction duct 2. Only the quantity of liquid required for detaching the soil to be removed is used. The operation of the cleaning device according to the invention is easily controlled by the fact that the upper face 13 of the bell 1 is transparent. Therefore, the operator sends only the number of pulses necessary for effective cleaning of the floor 3; this therefore results in a significant saving in the cleaning agent and consequently greater autonomy of the device according to the invention, which is particularly important when it is carried by a motorcycle.

Les figures 9 à 11 représentent une vanne disposée sur le conduit d'aspiration 2. Compte tenu de la nature des souillures à prélever, il est nécessaire que le conduit présente une section importante et constante c'est-à-dire sans étranglement jusqu'au réservoir de stockage des eaux usées. Conformément à l'invention le conduit 2 comporte une partie sensiblement cylindrique déformable 65 tel qu'un tuyau en caoutchouc, cette section en paroi souple 65 est soumise à l'action d'un organe de pincement comportant deux bras symétriques 66 articulés chacun autour d'un axe parallèle à l'axe du tuyau 67 et 68. La fermeture de la vanne ainsi constituée est obtenue en refermant les deux bras 66 sur le tuyau 65 de manière à l'aplatir dans la position représentée en 65' sur la figure 9, position dans laquelle les parois intérieures opposées sont en contact.Figures 9 to 11 show a valve disposed on the suction duct 2. Given the nature of the contamination to be removed, it is necessary for the duct to have a large and constant section, that is to say without constriction up to to the waste water storage tank. According to the invention, the conduit 2 comprises a substantially cylindrical deformable part 65 such as a rubber hose, this flexible wall section 65 is subjected to the action of a pinching member. comprising two symmetrical arms 66 each articulated about an axis parallel to the axis of the pipe 67 and 68. The closure of the valve thus formed is obtained by closing the two arms 66 on the pipe 65 so as to flatten it in the position shown at 65 ′ in FIG. 9, position in which the opposite interior walls are in contact.

Le dispositif de commande de cette vanne représenté en particulier à la figure 11 comporte essentiellement un câble 69 constituant un dispositif de Bowden. Ce câble entraîne un bras 71 solidaire en rotation d'un des bras de pincement 66; le mouvement en synchronisme des deux bras 66 est obtenu au moyen de deux pignons 72 et 73 solidaires de chacun d'un des bras 66 et s'engrenant l'un avec l'autre.The control device for this valve shown in particular in FIG. 11 essentially comprises a cable 69 constituting a Bowden device. This cable drives an arm 71 integral in rotation with one of the gripping arms 66; the movement in synchronism of the two arms 66 is obtained by means of two pinions 72 and 73 integral with each of one of the arms 66 and meshing with one another.

Avantageusement, la vanne ainsi constituée est logée dans une enceinte 74 entourant complètement le tuyau 65 et constituée de deux demi-coquilles75 et 76 comportant une partie saillante 77 pour le logement du dispositif de commande. Ces deux demi-coquilles sont fixées de manière étanche à la fois sur le conduit 2 et l'une sur l'autre de manière à réaliser autour de la vanne décrite ci-dessus une enceinte fermée étanche qui est reliée à la turbine d'aspiration du dispositif d'aspiration des eaux usées ceci permet d'équilibrer les pressions à l'intérieur et à l'extérieur du tuyau souple 65 et d'éviter que celui-ci ne se déforme en posi- tion d'ouverture sous l'effet de la dépression interne.Advantageously, the valve thus formed is housed in an enclosure 74 completely surrounding the pipe 65 and made up of two half-shells 75 and 76 comprising a projecting part 77 for housing the control device. These two half-shells are fixed in a sealed manner both on the duct 2 and one on the other so as to produce around the valve described above a sealed closed enclosure which is connected to the suction turbine. of the wastewater suction device, this makes it possible to balance the pressures inside and outside the flexible hose 65 and to prevent it from deforming in the open position under the effect internal depression.

On voit que cette vanne est d'une structure simple et qu'elle permet d'assurer une grande section de passage pour l'éjection aspirée.It can be seen that this valve is of a simple structure and that it ensures a large passage section for the suction ejection.

L'enceinte 74 est avantageusement en matière translucide, ce qui permet de contrôler le bon fonctionnement de la vanne 70.The enclosure 74 is advantageously made of translucent material, which makes it possible to control the proper functioning of the valve 70.

Avantageusement, comme cela sera décrit en détail plus bas, cette vanne est commandée de manière automatique par le mouvement de la cloche d'aspiration, la vanne étant ouverte lorsque cettæ cloche d'aspiration vient en position opérationnelle et se refermænt lorsque cette cloche revient en position de repos. De cette manière on assure que la turbine d'aspiration ne débite que pendant le fonctionnement du dispositif de nettoyage selon l'invention.Advantageously, as will be described in detail below, this valve is automatically controlled by the movement of the suction bell, the valve being open when this suction bell comes into operational position and closes when this bell returns. rest position. In this way it is ensured that the suction turbine only flows during the operation of the cleaning device according to the invention.

Le dispositif de nettoyage qui vient d'être décrit peut être monté sur tout engin mobile susceptible de se déplacer sur un trottoir; en particulier, comme cela est représenté sur la figure 12, il peut être monté sur une moto 16. Dans ce cas il est avantageux que l'on prévoie un dispositif de nettoyage de part et d'autre de la moto c'est-à-dire à droite et à gauche pour permettre à l'opérateur de travailler à droite ou à gauche de la moto ce qui lui permet d'opérer près d'obstacles et lui évite d'effectuer des demi-tours sur le trottoir. L'opérateur peut alors utiliser indifféremment l'un et l'autre des dispositifs de nettoyage de gauche ou de droite.The cleaning device which has just been described can be mounted on any mobile machine capable of moving on a sidewalk; in particular, as shown in Figure 12, it can be mounted on a motorcycle 16. In this case it is advantageous that there is provided a cleaning device on either side of the motorcycle that is - say to the right and to the left to allow the operator to work on the right or on the left of the motorbike which allows him to operate near obstacles and avoids him making U-turns on the sidewalk. The operator can then use either of the left or right cleaning devices.

Comme on peut le voir sur la figure 12, la cloche d'aspiration 1 de chaque dispositif de nettoyage est portée par un bras 78 articulé autour d'un axe horizontal 79 solidaire de la fourche avant de la moto 16; le déplacement de la position de repos, représentée sur la figure 12,à la position de travail est obtenue au moyen d'un vérin électrique 81 dont une des extrémités est solidaires de la fourche avant de la moto et l'autre est fixée sur le bras 78. L'axe 79 est le vérin 81 sont fixés sur une pièce de forme générale triangulaire 82 accrochée sur la fourche avant de la moto 16.As can be seen in FIG. 12, the suction bell 1 of each cleaning device is carried by an arm 78 articulated around a horizontal axis 79 secured to the front fork of the motorcycle 16; the displacement from the rest position, shown in Figure 12, to the working position is obtained by means of an electric actuator 81, one of the ends of which is secured to the front fork of the motorcycle and the other is fixed to the arm 78. The axis 79 and the jack 81 are fixed to a part of generally triangular shape 82 hung on the front fork of the motorcycle 16.

On voit également sur la figure 12 la vanne 70 du conduit d'aspiration 2 qui communique avec le réservoir des eaux usés 31 qui présente la forme générale d'un U entourant la roue arrière 32. Une ligne en trait mixte 83 schématise le câble de commande 69 de la vanne 70; ce câble est relié au bras 78 support de la cloche d'aspiration 1.We also see in Figure 12 the valve 70 of the suction pipe 2 which communicates with the waste water tank 31 which has the general shape of a U surrounding the rear wheel 32. A dashed line 83 shows schematically the cable control 69 of valve 70; this cable is connected to the arm 78 supporting the suction bell 1.

La moto 16 a été aménagée pour le fonctionnement du dispositif de nettoyage de l'invention. En particulier elle comporte à l'arrière un ensemble 84 comprenant en particulier la pompe haute pression d'alimentation des buses et le compresseur permettant d'obtenir la dépression dans le réservoir 31 des eaux usées. Avantageusement, la moto 16 comporte un dossier 85, ce qui permet à l'opérateur d'avoir une meilleure assise pour travailler. Avantageusement on dispose un réservoir plat 86 dans ce dossier 85. Ce réservoir peut être utilisé en tant que réservoir de carburant, le réservoir de carburant normal 87 étant utilisé pour contenir l'eau de nettoyage.The motorcycle 16 has been arranged for the operation of the cleaning device of the invention. In particular, it comprises at the rear an assembly 84 comprising in particular the high pressure pump supplying the nozzles and the compressor making it possible to obtain the vacuum in the water reservoir 31 worn. Advantageously, the motorcycle 16 has a backrest 85, which allows the operator to have a better seat for working. Advantageously, there is a flat tank 86 in this file 85. This tank can be used as a fuel tank, the normal fuel tank 87 being used to contain the cleaning water.

La figure 13 représente en détail la fixation de la cloche d'aspiration 1 sur la fourche avant 88 de la moto 16. Avantageusement, la cloche 1 est montée sur le bras 78 au moyen d'une articulation à rotule 89, ce qui permet à la cloche 1 d'épouser parfaitement le profil du terrain par l'intermédiaire de son joint 15 dans sa position de travail représentée en 1' sur la figure 13.FIG. 13 shows in detail the attachment of the suction bell 1 to the front fork 88 of the motorcycle 16. Advantageously, the bell 1 is mounted on the arm 78 by means of a ball joint 89, which allows the bell 1 to perfectly fit the profile of the ground by means of its seal 15 in its working position represented at 1 'in FIG. 13.

Le mouvement du bras 78 est commandé par le vérin électrique 81 qui comporte des interrupteurs de fin de course réglables. Pour des raisons de sécurité, il est interessant de prévoir un dispositif de maintien du vérin électrique 81 en position de repos; ce dispositif est du type électrique; il commande de manière automatique le mouvement de remontée du vérin dès que le bras 78 quitte sa position de repos. De cette manière on évite tout incident pouvant être créé par les secousse subies par la moto lorsqu'elle circule en particulier lors de la descente ou de la montée des trottoirs. Les interrupteurs de fin de course en bas du vérin 81 permettent d'adapter le dispositif selon l'invention au profil du terrain qui peut par exemple être en pente.The movement of the arm 78 is controlled by the electric actuator 81 which includes adjustable limit switches. For security reasons, it is interesting to provide a device for holding the electric actuator 81 in the rest position; this device is of the electrical type; it automatically controls the raising movement of the jack as soon as the arm 78 leaves its rest position. In this way, any incident that may be created by the jolts suffered by the motorcycle when it is traveling, in particular when descending or ascending the sidewalks, is avoided. The limit switches at the bottom of the jack 81 make it possible to adapt the device according to the invention to the profile of the terrain which can for example be sloping.

Comme indiqué ci-dessus, le mouvement du bras 78 commande de manière automatique la vanne 70. A cet effet, l'autre extrémité du câble 69 est fixée à l'extrémité arrière du bras 78. On peut prévoir en particulier que le mouvement d'ouverture de la vanne 70 débute lorsque le bras a déjà parcouru un tiers de sa course vers sa position de travail. De ce fait, le dispositif d'aspiration des eaux usées ne peut débiter que lorsque la cloche est en position de travail.As indicated above, the movement of the arm 78 automatically controls the valve 70. For this purpose, the other end of the cable 69 is fixed to the rear end of the arm 78. Provision may in particular be made for the movement d opening of the valve 70 begins when the arm has already traveled a third of its course towards its working position. As a result, the wastewater suction device can only flow when the bell is in the working position.

Selon une caractéristique de l'invention, les organes de commande normaux de la moto 16 sont également utilisés pour la commande du fonctionnement des deux dispositifs de nettoyage de droite et de gauche. A cet effet, on prévoit un commutateur qui nepeut agir que lorsque la moto se trouve à l'arrêt et qui, d'une part, commande l'allumage d'un girophare et de feu de détresse et, d'autre part, agit sur certains organes de commande de la moto pourqu'ils commandent le fonctionnement du dispositif de nettoyage. Ainsi, si l'on actionne ce commutateur "route/travail" la commande de clignotant sert au mouvement de descente de l'un ou l'autre des deux dispositifs de nettoyage de droite ou de gauche, la commande des clignotants de gauche commandant alors la descente du dispositif de nettoyage de gauche et la commande des clignotants de droite le mouvement de descente du dispositif de droite, le retour en position neutre commandant la remontée du dispositif de nettoyage concerné. Par ailleurs, l'actionnement du bouton poussoir d'avertisseur sonore commande l'envoi d'impulsions de liquide dans la buse 4. Enfin l'actionnement du bouton d'arrêt du moteur par mise en cours circuit de la bougie permet de sélectionner soit la buse 4 d'aspersion (position marche), soit la buse de balayage 14 dans le cas de sol sablonneux (position arrêt-moteur). Ceci permet de limiter le nombre des organes de commande se trouvant sur la moto tout en assurant un fonctionnement normal de celle-ci lorsqu'elle se déplace sur route.According to a characteristic of the invention, the normal control members of the motorcycle 16 are also used for controlling the operation of the two cleaning devices right and left. For this purpose, a switch is provided which can only act when the motorcycle is stationary and which, on the one hand, controls the lighting of a beacon and hazard warning light and, on the other hand, acts on certain motorcycle controls so that they control the operation of the cleaning device. Thus, if this "road / work" switch is actuated, the turn signal control is used to lower one or the other of the two cleaning devices on the right or on the left, the left turn signal control then controlling the lowering of the left-hand cleaning device and the control of the right-hand indicators the lowering movement of the right-hand device, the return to neutral position controlling the ascent of the cleaning device concerned. Furthermore, the actuation of the horn button pushes the sending of liquid pulses into the nozzle 4. Finally, the actuation of the engine stop button by switching on the spark plug circuit makes it possible to select either the spray nozzle 4 (on position), or the sweep nozzle 14 in the case of sandy soil (engine stop position). This makes it possible to limit the number of control members located on the motorcycle while ensuring normal operation of the latter when it is traveling on the road.

Conformément à l'invention, l'ensemble des organes actifs du dispositif de nettoyage selon l'invention, c'est à dire le compresseur du dispositif d'aspiration et la pompe d'alimentation des buses,est entraîné par le moteur de la moto qui comporte une sorte de "prise de force" au moyen d'une transmission par chaîne schématisée en 91 sur la figure 6. Cette transmission comporte un embrayage commandé par le commutateur "route/travail" précité. Compte-tenu du faible couple à transmettre, cet embrayage peut être un embrayage de type électromagnétique qui peut être facilement logé dans une poulie. Avantageusement, l'ensemble de commande du dispositif de nettoyage comporte également un alternateur alimentant une batterie pour l'alimentation du vérin électrique 81.In accordance with the invention, all of the active members of the cleaning device according to the invention, that is to say the compressor of the suction device and the nozzle supply pump, are driven by the motor of the motorcycle. which comprises a kind of "PTO" by means of a chain transmission shown diagrammatically at 91 in FIG. 6. This transmission comprises a clutch controlled by the aforementioned "road / work" switch. Given the low torque to be transmitted, this clutch can be an electromagnetic type clutch which can be easily accommodated in a pulley. Advantageously, the control assembly of the cleaning device also includes an alternator supplying a battery for supplying the electric actuator 81.

A titre d'accessoires, on peut brancher une lance sur la pompe haute-pression d'alimentation en liquide de nettoyage ce qui permet de décrocher et de déplacer par exemple dans le caniveau des souillures placées dans des endroits inaccessibles tels que par exemple entre deux voitures en stationnement.As accessories, you can connect a launches on the high-pressure pump for supplying cleaning liquid, which makes it possible to unhook and move, for example in the gutter, stains placed in inaccessible places such as, for example, between two parked cars.

Le fonctionnement du dispositif de nettoyage qui vient d'être décrit est le suivant. Lorsque le commutateur "route/travail" est en position route, la moto se trouve dans des conditions normales de circulation et ces organes de commande agissent de manière normale sur les différents éléments de la moto.The operation of the cleaning device which has just been described is as follows. When the "road / work" switch is in the road position, the motorcycle is in normal traffic conditions and these control members act in a normal manner on the various elements of the motorcycle.

Lorsque l'opérateur arrive à un endroit à nettoyer il arrête sa moto, met le commutateur précité en position travail, ce qui déclenche le fonctionnement du girophare et des feux de détresse et commande l'embrayage du dispositif d'entraînement des têtes de nettoyage. L'opérateur peut alors sélectionner la buse d'aspersion 4 ou la buse de balayage 14 au moyen du bouton d'arrêt du moteur, faire descendre la tête de nettoyage de droite ou de gauche au moyen de la commande de clignotant ce qui entraîne automa- ; tiquement l'ouverture de la vanne 70 de la tête en descente, qui se trouve donc reliée à la source d'aspiration. L'opérateur augmente alors le régime du moteur de la moto et il appuiesur la commande de l'avertisseur sonore pour envoyer des impulsions dans la buse et commander son balayage. Lorsqu'il constate visuellement à travers la partie supérieure 13 de la cloche que l'opération est terminée il remonte la tête de nettoyage, ce qui ferme la vanne 70 et il peut; alors se déplacer pour nettoyer une autre souillure. La commande de l'alimentation des buses par un organe monostable de manière à obtenir des impulsions de jets permet de n'utiliser que le seul liquide nécéssaire au nettoyage aucun liquide n'étant projeté pendant le mouvement de retour de la buse 4; il est même possible d'effectuer une aspiration sans injection d'eau lorsque l'aspiration suffit pour nettoyer le sol.When the operator arrives at a place to be cleaned, he stops his motorcycle, puts the aforementioned switch in the working position, which triggers the operation of the beacon and the hazard lights and controls the clutch of the cleaning heads drive device. The operator can then select the spray nozzle 4 or the sweep nozzle 14 by means of the engine stop button, lower the cleaning head from right or left by means of the flashing control, which causes automa -; tick opening the valve 70 of the head down, which is therefore connected to the suction source. The operator then increases the engine speed of the motorcycle and presses the horn control to send pulses into the nozzle and control its sweeping. When he visually finds through the upper part 13 of the bell that the operation is complete, he goes up the cleaning head, which closes the valve 70 and he can; then move to clean up another stain. The control of the supply of the nozzles by a monostable member so as to obtain jets pulses makes it possible to use only the only liquid necessary for cleaning, no liquid being sprayed during the return movement of the nozzle 4; it is even possible to perform a suction without injecting water when the suction is sufficient to clean the floor.

Du fait du faible poids de la tête de nettoyage à titre d'exemple la demanderesse a réalisé unetête qui ne pèse que 2,5 kg, le maniement du dispositif ne nécessite pas d'effort importa ce qui permet de réaliser une commande manuelle du passage de la position de travail à la position repos.Due to the low weight of the cleaning head, for example, the applicant has produced a head which weighs only 2.5 kg, the handling of the device does not require any significant effort, which makes it possible to carry out manual control of the passage. of the working position at rest position.

Le fait d'obtenir en position repos une moto qui ne soit pas modifiée en ce qui concerne ses capacités de circulation, est important, en particulier dans le cas où cette moto est utilisée pour nettoyer les trottoirs; en effet, il est important dans ce cas que la garde au sol ne soit pas réduite par le dispositif.Obtaining in a rest position a motorbike which is not modified as regards its circulation capacities, is important, in particular in the case where this motorbike is used to clean the sidewalks; in fact, it is important in this case that the ground clearance is not reduced by the device.

On voit donc que l'invention permet de réaliser un dispositif de nettoyage sur moto qui ne nécessite qu'un organe de commande supplémentaire, à savoir le commutateur "route/travail" ceci réduit le coût de fabrication et facilite l'emploi de la moto.It can therefore be seen that the invention makes it possible to produce a cleaning device on a motorbike which requires only an additional control member, namely the "road / work" switch, this reduces the manufacturing cost and facilitates the use of the motorbike. .

Par ailleurs, la consommation d'eau est réduite au minimum nécessaire pour le nettoyage du sol. Enfin, le dispositif de nettoyage de l'invention n'utilise que l'énergie qui est strictement nécessaire puisque ses parties mobiles ne sont mises en rotation que dans la position travail et que l'actionnement automatique de la vanne du conduit d'aspiration évite que le dispositif d'aspiration ne fonctionne à vide.In addition, water consumption is reduced to the minimum necessary for cleaning the floor. Finally, the cleaning device of the invention uses only the energy which is strictly necessary since its moving parts are only rotated in the working position and the automatic actuation of the valve of the suction duct avoids that the suction device does not operate empty.
