Definitions

  • the present invention relates to a mobile machine for projecting onto a fixed surface a jet of liquid, for example paint for the purpose of tracing a colored line. More specifically, the invention relates to a machine for drawing lines by spraying liquid paint and joint movement, mainly intended for tracing the limits of the playing areas of a sports field.
  • STATE OF THE ART EP 302 037 discloses a machine for tracing bands on a sports field in order to delimit the playing areas, these bands being formed by spraying a liquid paint.
  • This marking machine is manually movable and comprises a chassis mounted on wheels, provided with an operating handle, on which are installed a paint tank and a pump in communication relation on the one hand with said tank and on the other hand with a spray nozzle installed at the front of the machine frame.
  • the pump of the peristaltic type, is engaged by its rotor with the axle of one of the undercarriages of the chassis.
  • the stator of this pump has, opposite the rotor, an arcuate surface with an arc of circumference on which the rollers of the rotor compress a suction and delivery tube for the paint.
  • an expansion tank of the closed type is provided upstream of the nozzle.
  • This expansion tank occupies a lower level relative to the bottom of the paint tank and includes a sealed chamber into which the delivery tube of the pump enters on the one hand and the nozzle supply tube on the other hand spray.
  • the spray nozzle When the spray nozzle is closed, the penetration of the paint into the vase compresses the mass of air it contains. The energy thus accumulated is then returned to the spraying circuit with a view, for example, to spraying paint without actuating the pump.
  • This expansion tank further includes a pressure gauge which informs the user of the pressure prevailing in the spraying circuit. In this way the user can know if the pressure is sufficient to start marking. The small amount of paint that the vase can absorb, apart from any paint spraying, prevents the machine from moving over considerable distances without making the peristaltic pump inoperative.
  • the stator is mounted mobile and can be angularly moved from its normal position of use by a deactivation mechanism.
  • This mechanism essentially comprises a traction cable, in a sheath, secured to a maneuvering handle fixed to the handle. The stator spacing movement takes place against the action of a return spring which tends to return said stator to its initial position, that is to say to the pump activation position.
  • This deactivation mechanism in practice, is also used to deactivate the pump when the machine is pulled backwards which prevents any backflow of paint to the tank. Disclosure of the invention Technical problem
  • the advantage of such a machine lies essentially in the fact that the flow rate at the pump outlet is closely related to the speed of its movement so that good marking regularity is obtained despite variations in movement speed.
  • this machine presents a number of problems.
  • the need to use a pump deactivation mechanism so that said machine can operate over a relatively large distance without triggering the spraying complicates its production and increases its cost price.
  • the presence of such a mechanism also increases maintenance work.
  • Another disadvantage of the machine is closely related to the nature of the paint used. The latter is usually obtained by dilution in water of a base paint in aqueous phase subject to sedimentation, so that a more or less long period of non-use of the machine results in a deposit of the paint on the bottom of the tank.
  • this machine is not provided with any means of automatic stirring of the paint before use so that if the user is not careful, only water lightly loaded with paint and therefore weakly colored will be sprayed.
  • Another disadvantage of this machine lies in the rapid clogging of the expansion tank and in the difficulty of cleaning the latter as well as the circuit of spray. Indeed, in contact with the air contained in the vase, we observe a more or less rapid drying of the paint and a deposit of dry matter on the walls of the vase. As the machine does not have any self-cleaning means, cleaning of the spraying circuit is not carried out or is improperly carried out.
  • Another disadvantage of this machine lies in the fact that lying on its side for maintenance, for example, paint present in the expansion tank and in the spraying circuit can flow back to the pressure gauge and close the latter so irreversible. This drawback results in the obligation to replace the pressure gauge.
  • the object of the present invention is to overcome the aforementioned drawbacks by implementing a machine of the aforementioned type for which there is no need to disengage the pump when it is moving forward with the spray nozzle closed, the pump then being used to stir the paint contained in the tank.
  • Another object of the present invention is to provide a self-cleaning machine.
  • Another object of the present invention is to provide a machine with particularly simple means to prevent paint from backing up towards the pressure gauge when it is lying on its side.
  • Another object of the present invention is to provide a machine with a simplified but solid chassis.
  • the machine for projecting onto the fixed horizontal surface on which it operates, a jet of liquid, for example paint with a view to the formation on this surface of a mark in the form of a line, said machine comprising a chassis, a front wheel train and a rear wheel train, a reservoir of liquid to be sprayed, at least one spray nozzle installed at the front and a pump of the peristaltic type comprising a rotor coupled to the axle of one of the two sets of wheels and a stator comprising a stator body comprising at gaze of the rotor and in a centered manner relative to the latter a bearing surface in an arc of a circumference of a circle on which a radially elastically deformable tubular element bears under the effect of the thrust of rollers which the rotor comprises, which tubular element is in communication relationship on the one hand with the reservoir of liquid to be sprayed via a suction tube and on the other hand with the spray nozzle via a liquid supply circuit , said
  • the machine has a water tank, the spray nozzle is removably attached to the front of the machine and the suction tube is removably mounted in the paint tank so that for cleaning the circuit, the suction tube can be immersed in the water tank and the nozzle can be arranged either in the water tank or in the paint tank.
  • the sealed capacity constituting the expansion vessel is constituted by a tubular element, wound on itself according to one or more vertical loops fixed to the machine, said tube receiving the pressure gauge at the end.
  • the geometric axis of winding of the vertical loops is horizontal and parallel to the axis of advance of the machine.
  • the metal chassis of the machine receives the axle of the rear wheel train as well as the maneuvering handle and supports a plastic shell fitted with the front wheel train, this shell receiving in particular the paint tank, water tank, spray nozzle and paint supply system.
  • the advantage of such a configuration lies in the fact that the thrust forces exerted on the operating handle are directly transmitted to the metal frame which constitutes the most solid part of the machine.
  • the hull only supports the weight of the paint and water tanks and does not undergo any thrust or support force, it may be made up of thin walls which are properly ribbed. As the rear wheel set is loaded by the pushing force exerted by the user on the maneuvering handle, the risk of slipping of the rear wheels is greatly reduced.
  • the rotor of the peristaltic pump is coupled to the rear axle. Any failure in the operation of the pump is thus avoided.
  • the pump rotor is in coupling relationship with the axle which carries it, by means of a ratchet mechanism which couples the rotor to the axle when the machine is driven forward and uncouples between the rotor and the axle when the machine is driven rearward. This avoids the reflux of the paint to the tank when the machine is driven backwards.
  • the stator of the pump is articulated to a support plate, fixed to the shell of the machine and is held in position around the rotor by an elastic member.
  • the machine in front of the spray nozzle is provided with a pallet comprising a lower horizontal lip, preferably straight, subject to come into contact with the surface to be painted in order to sweep it .

Cette machine à tracer est déplaçable manuellement et comprend un châssis monté sur roues, pourvu d'une anse de manoeuvre, sur lequel sont installés un réservoir de peinture et une pompe en relation de communication d'une part avec ledit réservoir et d'autre part avec une buse de pulvérisation installée à l'avant du châssis de la machine. La pompe, du type péristaltique, est en prise par son rotor avec l'essieu de l'un des trains de roues du châssis. Le stator de cette pompe présente en regard du rotor une surface arquée en arc de circonférence de cercle sur laquelle les rouleaux du rotor compriment un tube d'aspiration et de refoulement de la peinture. Pour absorber la pression et le débit de la pompe alors que la buse est encore fermée est prévu en amont de la buse, un vase d'expansion du type fermé. Ce vase d'expansion, occupe un niveau inférieur par rapport au fond du réservoir de peinture et comprend une chambre étanche dans laquelle pénètre d'une part le tube de refoulement de la pompe et d'autre part le tube d'alimentation de la buse de pulvérisation. Lorsque la buse de pulvérisation est fermée, la pénétration de la peinture dans le vase comprime la masse d'air que contient ce dernier. L'énergie ainsi accumulée est ensuite restituée au circuit de pulvérisation en vue par exemple d'assurer une pulvérisation de peinture sans actionnement de la pompe. Ce vase d'expansion comporte en outre un manomètre qui renseigne l'utilisateur sur la pression régnant dans le circuit de pulvérisation. Par ce biais l'utilisateur peut savoir si la pression est suffisante pour débuter le marquage. La faible quantité de peinture que peut absorber le vase, en dehors de toute pulvérisation de peinture, interdit le déplacement de la machine sur des distances conséquentes sans rendre inopérante la pompe péristaltique. Pour ce faire le stator est monté mobile et peut être angulairement écarté de sa position normale d'utilisation par un mécanisme de désactivation. Ce mécanisme comprend essentiellement un câble de traction, sous gaine, solidarisé à une poignée de manœuvre fixée à l'anse. Le mouvement d'écartement du stator s'effectue à rencontre de l'action d'un ressort de rappel qui tend à ramener ledit stator dans sa position initiale c'est-à-dire dans la position d'activation de la pompe. Ce mécamsme de désactivation, dans la pratique, est aussi utilisé pour désactiver la pompe lorsque la machine est tractée vers l'arrière ce qui évite tout reflux de peinture vers le réservoir. Divulgation de l'invention Problème technique L'intérêt d'une telle machine réside essentiellement dans le fait que le débit en sortie de pompe est en étroite relation avec la vitesse de son déplacement de sorte que l'on obtient une bonne régularité de marquage malgré des variations de la vitesse de déplacement. Cependant cette machine présente un certain nombre de problèmes. Notamment la nécessité d'utiliser un mécamsme de désactivation de la pompe pour que ladite machine puisse évoluer sur une distance relativement importante sans déclenchement de la pulvérisation, complexifie sa réalisation et augmente son coût de revient. Par ailleurs la présence d'un tel mécanisme augmente aussi les travaux d'entretien. Un autre inconvénient de la machine est étroitement hé à la nature de la peinture utilisée. Cette dernière est habituellement obtenue par dilution dans de l'eau d'une peinture de base en phase aqueuse sujette à sédimentation, de sorte qu'une période plus ou moins longue d' inutilisation de la machine se traduit par un dépôt de la pemture sur le fond du réservoir. Or cette machine n'est dotée d'aucun moyen d'agitation automatique de la peinture avant utilisation de sorte que si l'utilisateur n'y prend pas garde, seule de l'eau faiblement chargée en peinture et donc faiblement colorée sera pulvérisée. La qualité du marquage s'en trouvera grandement affectée. Un autre inconvénient de cette machine réside dans le colmatage rapide du vase d'expansion et dans la difficulté de nettoyer ce dernier ainsi que le circuit de pulvérisation. En effet au contact de l'air contenu dans le vase, on observe un séchage plus ou moins rapide de la peinture et un dépôt de matières sèches sur les parois du vase. Comme la machine n'est dotée d'aucun moyen d'autonettoyage, le nettoyage du circuit de pulvérisation n'est pas effectué ou est mal effectué. Un autre inconvénient de cette machine réside dans le fait que couchée sur le côté en vue de son entretien par exemple, de la peinture présente dans le vase d'expansion et dans le circuit de pulvérisation peut refluer vers le manomètre et obturer ce dernier de manière irréversible. Cet inconvénient se traduit par l'obligation de remplacer le manomètre. Enfin la conception du châssis de la machine, sous forme de cadre en éléments métalliques soudés, accroît notablement le coût de cette dernière, alors que les efforts qu'elle supporte sont relativement peu importants et ne nécessitent pas une telle conception. Solution technique La présente invention a pour objet de pallier les inconvénients précédemment cités en mettant en œuvre une machine du genre précité pour laquelle il n'est nul besoin de débrayer la pompe lorsqu'elle évolue en marche avant avec la buse de pulvérisation fermée, la pompe étant alors utilisée pour brasser la peinture contenue dans le réservoir. Un autre but de la présente invention est de proposer une machine autonettoyante. Un autre but de la présente invention est de proposer une machine avec des moyens particulièrement simples pour éviter que de la peinture ne reflue vers le manomètre lorsqu'elle est couchée sur le côté. Un autre but de la présente invention est de proposer une machine avec un châssis simplifié mais solide. À cet effet, la machine selon l'invention, pour projeter sur la surface horizontale fixe sur laquelle elle évolue, un jet de liquide, par exemple de la peinture en vue de la formation sur cette surface d'une marque sous forme de ligne, ladite machine comportant un châssis, un train de roues avant et un train de roues arrière, un réservoir de liquide à pulvériser, au moins une buse de pulvérisation installée à l'avant et une pompe du genre péristaltique comportant un rotor accouplé à l'essieu de l'un des deux trains de roues et un stator comportant un corps de stator comprenant en regard du rotor et de manière centrée par rapport à ce dernier une surface d'appui en arc de circonférence de cercle sur laquelle prend appui un élément tubulaire déformable radialement de manière élastique sous l'effet de la poussée de rouleaux que comporte le rotor, lequel élément tubulaire est en relation de communication d'une part avec le réservoir de liquide à pulvériser par rentremise d'un tube d'aspiration et d'autre part avec la buse de pulvérisation par l'intermédiaire d'un circuit d'alimentation en liquide, ladite buse ou ledit circuit comportant un organe de commande de la circulation du liquide à pulvériser, commandé à distance par Intermédiaire d'un mécanisme de manœuvre et pouvant prendre à la commande une position d'ouverture permettant la pulvérisation du liquide et une position de fermeture interdisant cette pulvérisation, se caractérise essentiellement en ce que ledit circuit d'alimentation en liquide à pulvériser comprend en amont de l'organe de commande de la circulation du liquide, un régulateur de pression comportant une entrée de liquide, une première sortie d'alimentation de la buse par l'intermédiaire de l'organe de commande de la circulation et une seconde sortie de liquide connectée au réservoir de liquide par un circuit de retour, ladite seconde sortie délivrant un flux de liquide vers le réservoir lorsque la pression du flux de liquide dans le régulateur devient égale ou supérieure à une valeur de calibrage, ledit circuit d'alimentation étant connecté en aval de la première sortie du régulateur de pression à une capacité étanche remplie d'air constituant vase d'expansion. Lors du trajet aller de la machine vers le lieu de pulvérisation, le fait de maintenir l'organe de commande la circulation de liquide en position de fermeture provoque dans l'ordre la pressurisation de l'air contenu dans la capacité étanche et lorsque la pression de tarage est atteinte, le retour du liquide vers le réservoir. Par ailleurs comme le circuit d'alimentation se trouve sous pression, la pulvérisation de la peinture débutera dès l'ouverture de l'organe de commande de la circulation de liquide. Comme la pompe se trouve délestée par ce retour vers le réservoir, du liquide qui est aspiré en continu dans ce même réservoir, aucune surpression du conduit de la pompe pouvant conduire à la détérioration de ce dernier par explosion n'est à craindre. S'agissant d'une peinture diluée dans de l'eau et dont la matière solide est sujette à sédimentation, le retour vers le réservoir et l'aspiration ont des effets de brassage, de mélange et d'homogénéisation de cette peinture dans le réservoir. Ainsi le dépôt qui est susceptible de s'être formé dans le réservoir par sédimentation sera mélangé de manière homogène au solvant en l'espèce l'eau et ce avant pulvérisation de la peinture. Selon une autre caractéristique de l'invention, la machine embarque un réservoir d'eau, la buse de pulvérisation est fixée de manière amovible à l'avant de la machine et le tube d'aspiration est monté de manière amovible dans le réservoir de peinture de façon qu'en vue du nettoyage du circuit, le tube d'aspiration puisse être plongé dans le réservoir d'eau et la buse puisse être disposée soit dans le réservoir d'eau soit dans le réservoir de peinture. Le nettoyage de la machine et plus précisément de la pompe et du circuit d'alimentation pourra se faire alors de manière automatique au cours du trajet retour de la machine vers son local technique. Selon une autre caractéristique de l'invention, la capacité étanche constituant vase d'expansion est constituée par un élément tubulaire, enroulé sur lui-même selon une ou plusieurs boucles verticales fixées à la machine, ledit tube recevant en extrémité le manomètre. Selon une disposition avantageuse de l'invention, l'axe géométrique d'enroulement des boucles verticales est horizontal et parallèle à l'axe d'avancement de la machine. Lorsque la machine est couchée sur le côté c'est-à-dire sur l'un de ses flancs latéraux, la ou les boucle (s) que forme le tube demeurent verticales. Pour cette raison, la peinture liquide ne peut refluer vers le manomètre, elle demeure toujours dans la partie inférieure des boucles. Selon une autre caractéristique de l'invention, le châssis métallique de la machine reçoit l'essieu du train de roues arrière ainsi que l'anse de manœuvre et supporte une coque en matière synthétique dotée du train de roues avant, cette coque recevant notamment le réservoir de peinture, le réservoir d'eau, la buse de pulvérisation et le circuit d'alimentation en peinture. L'avantage d'une telle configuration réside dans le fait que les efforts de poussées exercés sur l'anse de manœuvre sont directement transmis au châssis métallique qui constitue la partie la plus solide de la machine. De surcroît comme la coque ne supporte que le poids des réservoirs de peinture et d'eau et ne subit aucun effort de poussée ou d'appui, elle pourra être constituée en parois minces correctement nervurées. Comme le train de roues arrière se trouve chargé par l'effort de poussée exercé par l'utilisateur sur l'anse de manœuvre, le risque de patinage des roues arrière se trouve fortement réduit. Pour cette raison, selon un autre aspect de l'invention, le rotor de la pompe péristaltique est accouplé à l'essieu arrière. Est évité ainsi tout raté dans le fonctionnement de la pompe. Selon une autre caractéristique de l'invention, le rotor de la pompe est en relation d'accouplement avec l'essieu qui le porte, par l'intermédiaire d'un mécanisme de cliquet qui réalise l'accouplement du rotor à l'essieu lorsque la machine est entraînée vers l'avant et réalise le désaccouplement entre le rotor et l'essieu lorsque la machine est entraînée vers l'arrière. Est évité ainsi le reflux de la peinture vers le réservoir lorsque la machine est entraînée vers l'arrière. Selon une autre caractéristique de l'invention, le stator de la pompe est articulé à une platine support, fixée à la coque de la machine et est maintenu en position autour du rotor par un organe élastique. Selon une autre caractéristique de l'invention, la machine en avant de la buse de pulvérisation est pourvue d'une palette comportant une lèvre inférieure horizontale, de préférence rectiligne, assujettie à venir au contact de la surface à peindre en- vue de la balayer.MOBILE MACHINE FOR PROJECTING ON A HORIZONTAL SURFACE FIXED A JET OF LIQUID, FOR EXAMPLE OF PAINTING, WITH A VIEW TO THE FORMATION OF A LINE. Technical Field The present invention relates to a mobile machine for projecting onto a fixed surface a jet of liquid, for example paint for the purpose of tracing a colored line. More specifically, the invention relates to a machine for drawing lines by spraying liquid paint and joint movement, mainly intended for tracing the limits of the playing areas of a sports field. STATE OF THE ART EP 302 037 discloses a machine for tracing bands on a sports field in order to delimit the playing areas, these bands being formed by spraying a liquid paint. This marking machine is manually movable and comprises a chassis mounted on wheels, provided with an operating handle, on which are installed a paint tank and a pump in communication relation on the one hand with said tank and on the other hand with a spray nozzle installed at the front of the machine frame. The pump, of the peristaltic type, is engaged by its rotor with the axle of one of the undercarriages of the chassis. The stator of this pump has, opposite the rotor, an arcuate surface with an arc of circumference on which the rollers of the rotor compress a suction and delivery tube for the paint. In order to absorb the pressure and the flow rate of the pump while the nozzle is still closed, an expansion tank of the closed type is provided upstream of the nozzle. This expansion tank occupies a lower level relative to the bottom of the paint tank and includes a sealed chamber into which the delivery tube of the pump enters on the one hand and the nozzle supply tube on the other hand spray. When the spray nozzle is closed, the penetration of the paint into the vase compresses the mass of air it contains. The energy thus accumulated is then returned to the spraying circuit with a view, for example, to spraying paint without actuating the pump. This expansion tank further includes a pressure gauge which informs the user of the pressure prevailing in the spraying circuit. In this way the user can know if the pressure is sufficient to start marking. The small amount of paint that the vase can absorb, apart from any paint spraying, prevents the machine from moving over considerable distances without making the peristaltic pump inoperative. To do this, the stator is mounted mobile and can be angularly moved from its normal position of use by a deactivation mechanism. This mechanism essentially comprises a traction cable, in a sheath, secured to a maneuvering handle fixed to the handle. The stator spacing movement takes place against the action of a return spring which tends to return said stator to its initial position, that is to say to the pump activation position. This deactivation mechanism, in practice, is also used to deactivate the pump when the machine is pulled backwards which prevents any backflow of paint to the tank. Disclosure of the invention Technical problem The advantage of such a machine lies essentially in the fact that the flow rate at the pump outlet is closely related to the speed of its movement so that good marking regularity is obtained despite variations in movement speed. However, this machine presents a number of problems. In particular the need to use a pump deactivation mechanism so that said machine can operate over a relatively large distance without triggering the spraying, complicates its production and increases its cost price. Furthermore, the presence of such a mechanism also increases maintenance work. Another disadvantage of the machine is closely related to the nature of the paint used. The latter is usually obtained by dilution in water of a base paint in aqueous phase subject to sedimentation, so that a more or less long period of non-use of the machine results in a deposit of the paint on the bottom of the tank. However, this machine is not provided with any means of automatic stirring of the paint before use so that if the user is not careful, only water lightly loaded with paint and therefore weakly colored will be sprayed. The quality of the marking will be greatly affected. Another disadvantage of this machine lies in the rapid clogging of the expansion tank and in the difficulty of cleaning the latter as well as the circuit of spray. Indeed, in contact with the air contained in the vase, we observe a more or less rapid drying of the paint and a deposit of dry matter on the walls of the vase. As the machine does not have any self-cleaning means, cleaning of the spraying circuit is not carried out or is improperly carried out. Another disadvantage of this machine lies in the fact that lying on its side for maintenance, for example, paint present in the expansion tank and in the spraying circuit can flow back to the pressure gauge and close the latter so irreversible. This drawback results in the obligation to replace the pressure gauge. Finally, the design of the machine chassis, in the form of a frame of welded metal elements, significantly increases the cost of the latter, while the forces it supports are relatively unimportant and do not require such a design. Technical solution The object of the present invention is to overcome the aforementioned drawbacks by implementing a machine of the aforementioned type for which there is no need to disengage the pump when it is moving forward with the spray nozzle closed, the pump then being used to stir the paint contained in the tank. Another object of the present invention is to provide a self-cleaning machine. Another object of the present invention is to provide a machine with particularly simple means to prevent paint from backing up towards the pressure gauge when it is lying on its side. Another object of the present invention is to provide a machine with a simplified but solid chassis. To this end, the machine according to the invention, for projecting onto the fixed horizontal surface on which it operates, a jet of liquid, for example paint with a view to the formation on this surface of a mark in the form of a line, said machine comprising a chassis, a front wheel train and a rear wheel train, a reservoir of liquid to be sprayed, at least one spray nozzle installed at the front and a pump of the peristaltic type comprising a rotor coupled to the axle of one of the two sets of wheels and a stator comprising a stator body comprising at gaze of the rotor and in a centered manner relative to the latter a bearing surface in an arc of a circumference of a circle on which a radially elastically deformable tubular element bears under the effect of the thrust of rollers which the rotor comprises, which tubular element is in communication relationship on the one hand with the reservoir of liquid to be sprayed via a suction tube and on the other hand with the spray nozzle via a liquid supply circuit , said nozzle or said circuit comprising a member for controlling the circulation of the liquid to be sprayed, remotely controlled by means of an operating mechanism and which can assume, when ordered, an open position allowing the spraying of the liquid and a position of closure preventing this spraying, is essentially characterized in that said liquid supply circuit to be sprayed comprises upstream of the liquid circulation control member, a pressure regulator comprising a liquid inlet, a first outlet for supplying the nozzle via the circulation control member and a second liquid outlet connected to the reservoir of liquid by a return circuit, said second outlet delivering a flow of liquid to the reservoir when the pressure of the liquid flow in the regulator becomes equal to or greater than a calibration value, said supply circuit being connected downstream of the first outlet of the pressure regulator to a sealed capacity filled with air constituting an expansion tank. During the outward journey from the machine to the spraying place, the fact of maintaining the control member the circulation of liquid in the closed position causes in order the pressurization of the air contained in the sealed capacity and when the pressure taring is reached, the liquid returns to the reservoir. Furthermore, since the supply circuit is under pressure, the spraying of the paint will start as soon as the liquid circulation control member is opened. As the pump is relieved by this return to the tank, of the liquid which is sucked continuously in this same tank, no overpressure of the pump duct can lead to the deterioration of the latter by explosion is to be feared. As this is a paint diluted in water and the solid matter of which is subject to sedimentation, the return to the tank and the suction have effects of mixing, mixing and homogenization of this paint in the tank. . So the deposit which is likely to have formed in the tank by sedimentation will be homogeneously mixed with the solvent in this case water and this before spraying the paint. According to another characteristic of the invention, the machine has a water tank, the spray nozzle is removably attached to the front of the machine and the suction tube is removably mounted in the paint tank so that for cleaning the circuit, the suction tube can be immersed in the water tank and the nozzle can be arranged either in the water tank or in the paint tank. The cleaning of the machine and more precisely of the pump and of the supply circuit can then be done automatically during the return journey from the machine to its technical room. According to another characteristic of the invention, the sealed capacity constituting the expansion vessel is constituted by a tubular element, wound on itself according to one or more vertical loops fixed to the machine, said tube receiving the pressure gauge at the end. According to an advantageous arrangement of the invention, the geometric axis of winding of the vertical loops is horizontal and parallel to the axis of advance of the machine. When the machine is lying on its side, that is to say on one of its lateral flanks, the loop or loops formed by the tube remain vertical. For this reason, the liquid paint cannot flow back towards the pressure gauge, it always remains in the lower part of the loops. According to another characteristic of the invention, the metal chassis of the machine receives the axle of the rear wheel train as well as the maneuvering handle and supports a plastic shell fitted with the front wheel train, this shell receiving in particular the paint tank, water tank, spray nozzle and paint supply system. The advantage of such a configuration lies in the fact that the thrust forces exerted on the operating handle are directly transmitted to the metal frame which constitutes the most solid part of the machine. In addition, as the hull only supports the weight of the paint and water tanks and does not undergo any thrust or support force, it may be made up of thin walls which are properly ribbed. As the rear wheel set is loaded by the pushing force exerted by the user on the maneuvering handle, the risk of slipping of the rear wheels is greatly reduced. For this reason, according to another aspect of the invention, the rotor of the peristaltic pump is coupled to the rear axle. Any failure in the operation of the pump is thus avoided. According to another characteristic of the invention, the pump rotor is in coupling relationship with the axle which carries it, by means of a ratchet mechanism which couples the rotor to the axle when the machine is driven forward and uncouples between the rotor and the axle when the machine is driven rearward. This avoids the reflux of the paint to the tank when the machine is driven backwards. According to another characteristic of the invention, the stator of the pump is articulated to a support plate, fixed to the shell of the machine and is held in position around the rotor by an elastic member. According to another characteristic of the invention, the machine in front of the spray nozzle is provided with a pallet comprising a lower horizontal lip, preferably straight, subject to come into contact with the surface to be painted in order to sweep it .

Meilleur mode de réalisation de l'invention. Telle que représentée, la machine selon l'invention, pour projeter sur la surface sur laquelle elle évolue, un jet de peinture liquide en vue de la formation sur cette surface d'un marquage sous forme de ligne, est déplaçable manuellement, de préférence, et comprend un châssis 1, métallique, recevant une anse de manœuvre 20, et un train 2 de roues arrière. Ce châssis 1 supporte une coque rigide 4 recevant un train de roues avant 3. Cette coque 4 supporte notamment un réservoir 5 de peinture liquide, une buse de pulvérisation 6 installée à l'avant de la machine et le stator 8 d'une pompe péristaltique 7 dont le rotor 9 est accouplé à l'essieu 2a du train de roues arrière par l'intermédiaire d'un mécamsme à cliquet 10 qui accouple le rotor 9 à l'essieu 2a lorsque la machine est poussée vers l'avant et qui le désaccouple lorsque la machine est tirée vers l'arrière, le rotor 9 étant fixé en translation sur l'essieu 2a. La pompe péristaltique 7, par son aspiration, est connectée à un tube d'aspiration 12 engagé de manière amovible dans le réservoir 5 et par son refoulement est connectée à un circuit 13 d'alimentation de la buse de pulvérisation 6. Le tube d'aspiration 12 possède un orifice d'aspiration amené au plus près du fond du réservoir. Le circuit d'alimentation 13 comporte un organe 14 de commande de la circulation de liquide, tel un robinet, manœuvré à distance depuis l'anse 20, par un mécanisme de manœuvre 15. Sous l'effet de l'action de l'utilisateur sur le mécamsme de manœuvre 15, le robinet 14 peut être disposé soit en position de fermeture pour interdire l'alimentation de la buse 6 soit en position d'ouverture pour autoriser l'alimentation de cette buse. Le châssis métallique 1 comprend par exemple deux étriers la métalliques supportant par l'intermédiaire de deux paliers 2b, l'essieu 2a du train de roues arrière. Ces deux étriers reçoivent en fixation l'anse 20 et la coque rigide 4. L'anse de manœuvre 20 reçoit l'effort de poussée ou de traction exercé par l'utilisateur dans le but de déplacer la machine vers l'avant ou vers l'arrière. Cette anse de manœuvre 20 est par exemple constituée par un tube cintré de façon à épouser sensiblement le contour d'un U. Cette anse de manœuvre 20 présente donc deux segments latéraux 20a destinés à être fixés aux deux étriers la du châssis 1 et un segment basai 20b constituant poignée de préhension. La coque rigide 4, obtenue par exemple par rotomoulage, est creuse et comprend une paroi supérieure 4a et une paroi inférieure 4b liées l'une à l'autre. Latéralement, la coque 4 comporte deux formes de garde-boue 4c qui constituent des nervures de rigidité. En partie inférieure, la coque 4 présente également deux nervures latérales de rigidité 4d. La coque 4 en partie supérieure, présente une ou plusieurs empreintes en creux prévues pour recevoir le ou les réservoirs, ainsi que les divers instruments nécessaires au fonctionnement et à l 'entretien de la machine. Selon la forme préférée de réalisation, chaque étrier la présente une section droite en U et comprend une aile basale lb et deux ailes latérales le. Les étriers métalliques, par leurs ailes latérales le, sont destinés à venir de part et d'autre respectivement des deux nervures latérales inférieures 4d de la coque 4 auxquelles ils sont fixés par boutonnage ou autres moyens. Sur l'extrados de son aile basale lb, chaque étrier la reçoit en fixation l'un des deux paliers 2b de l'essieu 2a. Préférentiellement, chaque palier 2b de l'essieu 2a est formé par un bloc en matière synthétique. À titre d'exemple, la matière utilisée pourra être celle connue sous le nom commercial de « Téflon ». De part et d'autre de l'un des paliers 2b, l'essieu 2a comporte deux bagues d'arrêt formant épaulements. Ces bagues d'arrêt ont pour but d'immobiliser l'essieu 2a en translation par rapport aux paliers 2b. Les roues arrière sont fixées à l'essieu 2a pour l'une en translation et rotation et pour l'autre en translation seulement de façon à pouvoir tourner par rapport à l'essieu. Chaque étrier la comporte en saillie sur l'intrados de son aile basale lb un pion fileté, saillant, prévu pour être engagé dans un perçage traversant pratiqué dans la paroi inférieure de la coque 4 et débouchant dans le volume interne de ladite coque. À l'opposé de ce perçage traversant la paroi supérieure de la coque 4 présente un autre perçage traversant par lequel est engagé dans le volume interne de la coque 4 un fourreau métallique 16 comportant en partie inférieure un taraudage. Par ce taraudage, le fourreau 16 est vissé au pion fileté de Pétrier la correspondant. Chaque fourreau 16 par son extrémité supérieure est en débordement par rapport à la coque 4. Dans les deux fourreaux 16 sont engagés respectivement les deux segments latéraux 20a de l'anse 20 de manœuvre. Préférentiellement, la partie en débordement de chaque fourreau 16 est équipée d'un mécanisme de blocage du segment correspondant de l'anse de manœuvre. Ce mécanisme de blocage est constitué par exemple par une vis pression engagée dans un taraudage traversant radial formé dans la partie débordante du fourreau et amenée en pression, par vissage, contre l'anse de manœuvre. Cette disposition assure d'une part l'immobilisation de l'anse, mais aussi autorise le réglage en hauteur de cette dernière. On comprend que grâce à la configuration du châssis 1, l'effort de poussée ou de traction exercé par l'utilisateur sur l'anse de manœuvre 20 est transmis intégralement à l'essieu 2a et aucunement à la coque 4. Cette disposition permet en outre, en reportant sur l'essieu 2a une partie de l'effort de poussée exercé par l'utilisateur sur l'anse de manœuvre 20, d'augmenter l'adhérence des roues arrière sur le sol et de vaincre le contre couple exercé par le rotor 9 de la pompe 7 sur l'essieu 2a. Ainsi en s'opposant au patinage des roues arrière, est écarté le risque d'un entraînement irrégulier du rotor 9 de la pompe 7. Le^stator 8 de la pompe péristaltique 7 comprend un corps de stator 8s, doté, en regard du rotor 9 et de manière centrée par rapport à ce dernier, d'une surface d'appui 8b, en arc de circonférence de cercle, sur laquelle prend appui, un élément tubulaire 11, radialement déformable de manière élastique sous l'effet de la poussée de rouleaux de pression 9a que comporte le rotor 9. Ces rouleaux de pression 9a sont régulièrement écartés les uns des autres. Chaque rouleau 9a réalise un pincement de l'élément tubulaire, la zone pincée se déplaçant avec le rouleau. Le pincement réalisé assure un cloisonnement étanche de l'élément tubulaire, ce cloisonnement s'opposant à tout passage de liquide au travers de la zone pincée. La valeur de l'arc de circonférence de cercle selon lequel se développe la surface d'appui 8b est supérieure à la valeur angulaire de l'arc de circonférence entre deux rouleaux de pression consécutifs de façon que l'élément tubulaire 11 soit toujours pincé par au moins un rouleau 9a. Cet élément tubulaire 11 est raccordé par son extrémité amont au tube d'aspiration 12 et par son extrémité aval au circuit 13 d'alimentation de la buse 6. Préférentiellement, le corps de stator 8a de la pompe 8 se présente sous la forme d'un arceau et est articulé par une de ses extrémités à une platine support 7a, fixée à la paroi inférieure de la coque 4. Par son autre extrémité, le corps de stator 8a coopère avec au moins un organe élastique 17. Sous l'effet de l'action de cet organe élastique, le stator 8a est maintenu en position autour du rotor 9. Préférentiellement, cette autre extrémité est pourvue d'au moins un perçage traversant dans lequel est engagée une tige filetée 18 solidarisée à la platine support 7a. En extrémité libre, cette tige filetée 18 reçoit en vissage un écrou de réglage et de maintien 19. L'organe élastique 17, constitué par un ressort à spires, est monté sur cette tige filetée entre le corps de stator 8a et l'écrou 19. Préférentiellement seront prévues deux tiges filetées 18, deux ressorts 17 et deux écrous 19. En vissant plus ou moins les écrous 19, il est possible de régler la force de pression des rouleaux 9a sur l'élément tubulaire 11 de la pompe 7. De surcroît, par démontage des écrous 19, il devient possible d'écarter angulairement le corps de stator, en vue par exemple du retrait ou de la mise en place de l'élément tubulaire 11. Cet élément tubulaire 11, réalisé de préférence en matière synthétique souple, est positionné sur la surface 8b et est engagé dans deux perçages traversants pratiqués dans le corps du stator 8a respectivement en amont et en aval de ladite surface 8b. H y a lieu de noter que la platine 7a et les paliers 2b support de l'essieu 2a sont fixes l'un par rapport à l'autre. Dans le cas où un affaissement de la paroi de la coque supportant la platine 7a est à craindre, un élément de renfort pourra être disposé entre cette paroi et les paliers 2b, cet élément de renfort pouvant, par exemple prendre la forme d'un arceau fixé d'une part à ladite paroi et d'autre part aux étriers la supportant les paliers 2b. Selon une disposition avantageuse de l'invention, le rotor 9 de la pompe 7 comprend un palier lisse 9b par lequel il est engagé sur l'essieu 2a et un flasque 9c fixé à ce palier lisse, ce flasque portant d'une part les rouleaux 9a, et d'autre part de manière articulée, le cliquet 10a du mécanisme à cliquet 10. Les rouleaux 9a sont montés de manière libre en rotation et fixe en translation sur des axes fixés en porte à faux sur le flasque 9c du rotor 9. Les rouleaux 9a et les axes qui les supportent sont parallèles à l'essieu 2a ainsi qu'à la surface d'appui 8b du corps de stator 8. Ces rouleaux 9a sont régulièrement écartés les uns des autres. Préférentiellement le rotor 9 comporte au moins trois rouleaux 9a. Le cliquet 10a est monté sur un pion fixé en porte à faux sur le flasque du rotor 9. Le cliquet 10a est prévu pour coopérer en engagement de forme avec des crans 10b formés dans l'essieu 2a. Le cliquet 10a est rappelé en position d'engagement dans les crans 10b par un organe élastique 10c tel un ressort à spires fixé d'une part au dit cliquet et d'autre part au flasque 9c du rotor 9. Le circuit 13 d'alimentation en peinture, comporte en amont du robinet 14 un régulateur de pression 21 comportant une entrée en relation de communication avec l'élément tubulaire 11 par rintermédiaire d'un filtre 22, une première sortie de peinture en relation de communication avec le robinet 14 et une deuxième sortie de peinture en relation de communication avec le réservoir par l'intermédiaire d'une conduite de retour 21a. Cette conduite de retour 21a possède un orifice de refoulement de peinture disposé au plus près du fond du réservoir de penture. Lorsque la valeur de la pression dans le régulateur 21 devient égale ou supérieure à la valeur de tarage de ce dernier, la seconde sortie du régulateur de pression 21, d'un état normalement fermé, passe à un état ouvert de sorte que le liquide débité par la pompe 7 peut retourner au réservoir 5, la communication entre l'entrée du régulateur et la première sortie étant toujours assurée. ' Ainsi, la machine peut évoluer en marche avant, sans qu'il soit nécessaire de délester la pompe par une pulvérisation. Comme dans ce cas de figure la pompe 7 se déleste dans le réservoir 5 et simultanément aspire la peinture liquide contenue dans ce dernier, on obtient de cette façon, avant pulvérisation, un brassage automatique de la peinture dans le réservoir 5 et un mélange homogène des différents constituants de la peinture. Pendant la pulvérisation, si la pression dans le régulateur 21 devient égale ou supérieure à la valeur de tarage, la seconde sortie passera à l'état d'ouverture et une partie du flux de peinture retournera au réservoir et l'autre partie du flux alimentera la buse 6. Avantageusement, en aval de la première sortie du régulateur 21 et en amont du robinet 14, le circuit d'alimentation 13 est associé à une capacité étanche 23 remplie d'air constituant vase d'expansion. Cette capacité 23 se trouve pressurisée par la montée en pression du circuit d'alimentation sous l'effet du débit de la pompe. Grâce à cette capacité 23, le circuit d'alimentation 13 de la buse 6, pour sa partie en amont du robinet 14 est toujours maintenue en pression de sorte que la pulvérisation débute dès que le robinet 14 est ouvert. La réserve d'énergie que constitue cette capacité 23 autorise ainsi une pulvérisation, la pompe 7 à l'arrêt. Cette caractéristique technique, combinée au fait que la buse de pulvérisation 6 et la partie aval au robinet 14 du circuit d'alimentation ne soient pas fixées à la structure de la machine mais simplement positionnées de manière amovible sur cette structure ce qui leur assure une latitude de déplacement par rapport à la machine, confère à ladite machine une grande souplesse d'utilisation. Ainsi l'utilisateur après avoir saisi la buse de pulvérisation pourra réaliser un traçage à la main ou bien un traçage à l'aide d'un pochoir, d'un point caractéristique de la surface à peindre. S'agissant du traçage des marques d'un terrain de sport par exemple un terrain de football, le traçage des lignes droites ou des grandes lignes courbes sera opéré en déplaçant la machine sur le terrain et en maintenant le robinet ouvert, la buse étant en place sur la structure. En revanche, le traçage des lignes de corner et des points de penalty, sera opéré la machine à l'arrêt, par l'utilisateur. La partie du circuit d'alimentation, en aval du robinet 13 sera constituée par un tube souple en matière synthétique d'une longueur suffisante pour réaliser ces traçages à la main. À titre d'exemple, cette longueur sera de l'ordre de 1,50 mètres à 2 mètres. Préférentiellement, la capacité 23 est constituée par un élément tubulaire, enroulé sur lui-même selon une ou plusieurs boucles verticales fixées à la machine. L'extrémité inférieure de cet élément tubulaire est raccordée au circuit d'alimentation 13 par un raccord en Té. L'extrémité supérieure de l'élément tubulaire se situe au- dessus de la ou des boucle(s) verticale(s) formée(s) et reçoit un manomètre 24. Cette extrémité supérieure est disposée de préférence selon un niveau de hauteur supérieur au niveau maximal de peinture dans le réservoir de façon que le manomètre 24 soit toujours disposé au-dessus de ce niveau. À titre d'exemple purement indicatif, pour constituer la capacité 23, sera utilisé un tube d'un diamètre interne d'environ 8 millimètres et d'une longueur de 2 mètres. Ces boucles verticales sont positionnées par rapport à la machine en sorte que leur axe d'enroulement soit horizontal et parallèle à l'axe d'avancement de la machine. En raison de cette disposition, les boucles, lorsque la machine est couchée sur le flanc demeurent verticales ce qui évite tout reflux de peinture vers le manomètre 24, la peinture se trouvant piégée dans la partie inférieure de la ou des boucle(s) verticale(s). Le fait de réaliser la capacité 23 à l'aide d'un élément tubulaire par exemple en 5 matière synthétique souple, alors que sur la machine de l'art antérieur est utilisé un vase d'expansion, permet une dύninution notable du coût de réalisation de la machine, et du coût d'entretien de cette dernière. Grâce au manomètre 24, qui indique en permanence la pression dans le circuit d'alimentation 13, il est possible de régler la valeur de tarage du régulateur de 10 pression 21 , ce dernier comportant des moyens de réglage à cet effet. Préférentiellement le manomètre 24 sera monté sur une platine fixée à l'anse 20 de manœuvre et ce au plus près de la forme de poignée 20b que cette dernière comporte, de façon à pouvoir être aisément lisible par l'utilisateur. Les boucles que forme l'élément tubulaire 23 seront avantageusement 15 disposées dans la coque 4 de la machine, dans une chambre que cette dernière comporte en partie arrière. Selon une forme préférée de réalisation, le mécanisme de manœuvre 15 comprend une poignée 15a, du type ambidextre, articulée à l'anse de manœuvre 20, un ' câble 15b sous gaine, fixé d'une part à la poignée 15a et d'autre part à un levier de 20 manœuvre 14a que possède le robinet 14 et un organe élastique 15c fixé d'une part au levier 14a du robinet de manœuvre 14 et d'autre part à la coque rigide 4, cet organe élastique sollicitant le levier de manœuvre 14a dans le sens de la fermeture du robinet 14. De préférence, la poignée 15a de manœuvre est en forme d'arceau et possède 25 deux tourillons d'extrémité par lesquels elle est engagée en articulation d'une part dans un perçage radial pratiqué dans l'un des segments latéraux 20a de l'anse 20 et d'autre part dans un perçage radial pratiqué dans l'autre segment latéral de l'anse, cette poignée 15a s'étendant d'un segment latéral à l'autre. À la poignée 15a de manœuvre est fixée une platine. À cette platine est fixée 30 l'extrémité correspondante du câble 15b. Par manœuvre de la poignée 15a vers le segment basai 20b de l'anse de manœuvre 20, est imprimé sur le câble 15b un effort de traction qui est communiqué au levier de manœuvre 14a du robinet 14. Sous l'effet de cet effort, le levier de manœuvre 14a est déplacé à l'encontre de l'action de l'organe élastique de rappel 15c d'une position correspondant à la fermeture du robinet 14 vers une position correspondant à l'ouverture de ce dernier pour autoriser l'alimentation de la buse 6 en peinture et par voie de conséquence la pulvérisation. Cette pulvérisation s'effectue normalement lorsque la machine est poussée vers l'avant par l'utilisateur mais elle peut aussi être effectuée à l'arrêt tant que l'air contenu dans la capacité 23 est à une pression suffisante. On comprend que pendant cette pulvérisation à l'arrêt, l'air contenu dans la capacité 23 se détend progressivement. Il y a lieu de noter que pendant la pulvérisation, la machine étant en marche à vitesse normale, la perte de charge au niveau de la buse d'une part et la pression du liquide débité par la pompe d'autre part sont suffisantes pour assurer la montée de liquide dans la capacité ce qui comprime l'air contenu dans cette dernière. Ainsi la capacité constitue réserve d'énergie et absorbe dans une certaine mesure les variations de pressions dues par exemple aux variations de la vitesse de la machine. La pulvérisation se produit tant que la poignée 15a est maintenue par l'utilisateur contre le segment basai 20b de l'anse de manœuvre. Dès que l'utilisateur relâche la poignée 15a, l'organe élastique 15c ramène le robinet en position de fermeture par action sur le levier 14a. Le câble 15b se trouve alors tiré par le levier 14a ce qui ramène la poignée 15a en position initiale. Pour maintenir la réserve 23 en pression pendant des périodes plus ou moins longues d'arrêt de la machine, il est utile d'écarter tout risque de reflux de liquide vers le réservoir via le tube 11 de la pompe et le tube d'aspiration 12. Ce reflux peut résulter d'une usure des rouleaux 9a ou du tube 11, telle que le pincement du tube par chaque rouleau ne s'effectue plus de manière correcte et autorise un passage du liquide au travers de la zone pincée. Dans ce but, est disposé sur le trajet de liquide, en amont du point de raccordement de la capacité 23 au circuit 13, un élément anti-retour 39. Cet élément anti-retour pourra être constitué par un clapet anti-retour. De préférence, dans un but de simplification, ce clapet anti-retour 39 est disposé sur le tube d'aspiration 12 comme on peut le voir sur les figures 1 et 2. Sur ces figures, on remarque que le clapet anti-retour 39 est disposé à distance de l'orifice d'aspiration que comporte le tube d'aspiration mais ce clapet anti-retour pourra être monté dans ledit orifice ou dans une crépine associée à ce dernier. Cette disposition évite le vidage de la partie de tube plongeant dans le réservoir. La buse de pulvérisation 6 est déportée latéralement par rapport à la machine de façon que le marquage effectué ne puisse pas être dégradé par le passage des roues ou par les pas de rutilisateur. Avantageusement la buse de pulvérisation 6 produira deux jets de peinture dont un sera dirigé vers l'avant de la machine et l'autre vers l'arrière. S'agissant d'une pulvérisation sur une surface engazonnée, cette disposition permet d'apposer la peinture sur les faces antérieures et postérieures des brins d'herbes en un seul passage. Préférentiellement la buse 6 est engagée de manière amovible dans un fourreau vertical 31 ouvert aux deux extrémités, porté par un support horizontal 26 solidarisé à une structure porteuse 30 fixée à la coque 4 de la machine. Ce support horizontal est transversal à la direction d'avancement de la machine. Préférentiellement la buse 6 est dotée d'un crochet 6a de suspension par lequel elle est suspendue au fourreau vertical 31. Avantageusement ce fourreau vertical 31 est monté de manière réglable en hauteur sur le support transversal 26. Cette disposition permet de régler la hauteur de la buse 6 par rapport au sol et par voie de conséquence la largeur de la ligne tracée, le jet en sortie de buse étant plat et triangulaire. Pour régler le déport latéral de la buse par rapport à la machine, la position du fourreau vertical 31 le long du support transversal 26 sera ajustable. Préférentiellement, de part et d'autre de la buse 6 et de son fourreau support 31 seront installés en fixation au support transversal 26, deux écrans 28 verticaux, sous forme de parois rectangulaires ou triangulaires, assujettis à venir par leur bord horizontal inférieur au plus près du sol. Ces écrans 28 constituent obstacle au vent, et ont pour but notamment de protéger le jet de peinture de l'action de ce dernier. Préférentiellement la machine est dotée d'une palette 28 disposée en avant de la buse 6, ladite palette comportant une lèvre inférieure assujettie à venir au contact de la surface à peindre en vue de la nettoyer par balayage et essentiellement en chasser la rosée. Selon une forme préférée d'exécution, au support transversal 26, latéralement au fourreau 31 , est fixé un second support 32 horizontal sous forme de barre rigide, s'étendant de manière parallèle à la direction d'avancement de la machine. Par son extrémité distale, ce support 32 porte en avant de la buse 6, par rintermédiaire d'une liaison élastique 33, la palette 34. Cette palette 34 sera avantageusement constituée en une matière synthétique élastiquement déformable. Préférentiellement, pour conférer à la palette en plus de l'effet de balayage un effet de chasse, cette dernière est disposée de manière oblique par rapport à la direction d'avancement de la machine. La liaison élastique 33 est avantageusement constituée par un ressort à boudin à spires jointives, fixé d'une part à l'extrémité distale du support horizontal 32 et d'autre part à la palette 34. Grâce à cette disposition de liaison élastique 33, la palette 34, lorsqu'elle rencontre un obstacle, qui peut par exemple être un poteau de but, peut facilement s'effacer face à l'obstacle, par déformation de la liaison élastique. Il devient donc possible de réaliser le marquage jusqu'à l'obstacle rencontré. Selon une première forme de réalisation, la structure porteuse 30 comprend un tube horizontal 35 fixé à la paroi inférieure 4b de la coque 4, ce tube comportant en extrémité avant une douille verticale dans laquelle est engagé et bloqué, par une vis pression, un embout vertical fixé au support transversal 26. Selon une autre forme de réalisation, la structure porteuse 30 comprend toujours le tube horizontal 35 fixé à la paroi inférieure 4b de la coque 4, ce tube comportant toujours en extrémité avant une douille verticale "dans laquelle est engagé et bloqué par une vis pression, un embout vertical fixé non plus au support transversal 26, mais à l'un des deux éléments 37 d'une articulation 36 d'axe horizontal et perpendiculaire au sens d'avancement de la machine. L'autre élément 38 de l'articulation est agencé en bras de levier et reçoit en extrémité distale d'une part le support transversal 26 et d'autre part un organe 27 d'appui au sol qui peut être constitué par une roue, par un patin de glissement ou autre. L'intérêt d'une telle disposition réside dans le fait que la buse 6 peut suivre les irrégularités du terrain si bien que la largeur de la ligne formée sera uniforme. La machine sera également équipée d'un réservoir d'eau 25 pour procéder au nettoyage de la pompe, du circuit d'alimentation et de la buse de pulvérisation 6. Pour procéder au nettoyage, le tube d'aspiration 12 sera plongé dans le réservoir d'eau 25 et la machine sera entraînée en marche avant. Ce nettoyage peut parfaitement être opéré immédiatement après le traçage, lors notamment du trajet de retour de la machine vers le local technique. En vue de ce nettoyage, le robinet 14 est ouvert par action sur la poignée 15a. Il convient de récupérer l'eau de nettoyage. Dans ce but la buse 6 est plongée dans le réservoir de peinture ou bien dans le réservoir d'eau. La machine telle que décrite est principalement destinée au marquage de terrains de sport engazonnés ou non, mais il va de soi qu'elle peut être utilisée pour la formation de marques sur tout autre type de surface par exemple sur des voies de circulation et autres. On a précédemment décrit une machine ne comportant qu'une seule buse de pulvérisation 6, mais il va de soi que cette machine pourra être équipée de plusieurs buses 6 connectées par exemple au même circuit d'alimentation 13 et montées par exemple sur le même support transversal 26. De même l'utilisation de la machine n'est pas limitée à la pulvérisation d'une peinture, ainsi la machine peut être utilisée pour la pulvérisation de liquides de traitement de surface tel que des désherbants, des engrais etc. H va de soi que la présente invention peut recevoir tous aménagements et variantes du domaine des équivalences techniques sans pour autant sortir du cadre du présent brevet. Best embodiment of the invention. As shown, the machine according to the invention, for projecting onto the surface on which it operates, a jet of liquid paint with a view to the formation on this surface of a marking in the form of a line, is preferably manually movable, and comprises a chassis 1, metallic, receiving a maneuvering handle 20, and a train 2 of rear wheels. This chassis 1 supports a rigid shell 4 receiving a front wheel train 3. This shell 4 supports in particular a reservoir 5 of liquid paint, a spray nozzle 6 installed at the front of the machine and the stator 8 of a peristaltic pump 7, the rotor 9 of which is coupled to the axle 2a of the rear wheel assembly by means of a ratchet mechanism 10 which couples the rotor 9 to the axle 2a when the machine is pushed forward and which uncouples when the machine is pulled back, the rotor 9 being fixed in translation on the axle 2a. The peristaltic pump 7, by its suction, is connected to a suction tube 12 removably engaged in the reservoir 5 and by its discharge is connected to a circuit 13 for supplying the spray nozzle 6. The tube suction 12 has a suction opening brought as close as possible to the bottom of the tank. The supply circuit 13 comprises a member 14 for controlling the circulation of liquid, such as a tap, operated remotely from the handle 20, by an operating mechanism 15. Under the effect of the action of the user on the operating mechanism 15, the valve 14 can be arranged either in the closed position to prevent the supply of the nozzle 6 or in the open position to allow the supply of this nozzle. The metal frame 1 comprises for example two metal stirrups supporting by means of two bearings 2b, the axle 2a of the rear wheel train. These two stirrups receive in fixing the handle 20 and the rigid shell 4. The maneuvering handle 20 receives the pushing or traction force exerted by the user in order to move the machine forward or towards the 'back. This maneuvering handle 20 is for example constituted by a bent tube so as to substantially match the contour of a U. This maneuvering handle 20 therefore has two lateral segments 20a intended to be fixed to the two stirrups 1a of the chassis 1 and a basal segment 20b constituting a grip handle. The rigid shell 4, obtained for example by rotational molding, is hollow and comprises an upper wall 4a and a lower wall 4b linked to one another. Laterally, the shell 4 has two forms of mudguard 4c which constitute stiffening ribs. In the lower part, the shell 4 also has two lateral ribs of rigidity 4d. The shell 4 in the upper part has one or more recesses imprinted to receive the tank or tanks, as well as the various instruments necessary for the operation and maintenance of the machine. According to the preferred embodiment, each stirrup has a U-shaped cross section and comprises a basal wing 1b and two lateral wings 1c. The metal stirrups, by their lateral wings le, are intended to come from either side of the two lower lateral ribs 4d of the shell 4 to which they are fixed by buttoning or other means. On the upper surface of its basal wing 1b, each stirrup receives it in fixing one of the two bearings 2b of the axle 2a. Preferably, each bearing 2b of the axle 2a is formed by a block of synthetic material. For example, the material used may be that known under the trade name of "Teflon". On either side of one of the bearings 2b, the axle 2a has two stop rings forming shoulders. The purpose of these stop rings is to immobilize the axle 2a in translation relative to the bearings 2b. The rear wheels are fixed to the axle 2a for one in translation and rotation and for the other in translation only so as to be able to rotate relative to the axle. Each stirrup has it projecting from the lower surface of its basal wing 1b, a threaded, projecting pin, intended to be engaged in a through hole made in the lower wall of the shell 4 and opening into the internal volume of said shell. In contrast to this hole passing through the upper wall of the shell 4 has another through hole through which is engaged in the internal volume of the shell 4 a metal sheath 16 having in the lower part a thread. By this tapping, the sleeve 16 is screwed to the corresponding Petrier threaded pin. Each sleeve 16 by its upper end projects beyond the shell 4. In the two sleeves 16 are engaged respectively the two lateral segments 20a of the handle 20 for maneuvering. Preferably, the projecting part of each sleeve 16 is equipped with a mechanism for blocking the corresponding segment of the operating handle. This locking mechanism is constituted for example by a pressure screw engaged in a radial through thread formed in the projecting part of the sheath and brought into pressure, by screwing, against the operating handle. This arrangement ensures on the one hand the immobilization of the handle, but also allows the height adjustment of the latter. It is understood that thanks to the configuration of the chassis 1, the thrust or traction force exerted by the user on the maneuvering handle 20 is transmitted entirely to the axle 2a and in no way to the hull 4. This arrangement allows further, by transferring to the axle 2a part of the thrust force exerted by the user on the maneuvering handle 20, to increase the grip of the rear wheels on the ground and to overcome the counter torque exerted by the rotor 9 of the pump 7 on the axle 2a. Thus by opposing the slipping of the rear wheels, the risk of an irregular drive of the rotor 9 of the pump 7 is eliminated. The ^ stator 8 of the peristaltic pump 7 comprises a stator body 8s, provided, facing the rotor 9 and centered with respect to the latter, a bearing surface 8b, in an arc of circumference of circle, on which is supported, a tubular element 11, radially deformable in an elastic manner under the effect of the thrust of pressure rollers 9a that comprises the rotor 9. These pressure rollers 9a are regularly spaced from one another. Each roller 9a pinches the tubular element, the pinched area moving with the roller. The pinching carried out ensures a tight partitioning of the tubular element, this partitioning opposing any passage of liquid through the pinched area. The value of the arc of circle circumference along which the bearing surface 8b develops is greater than the angular value of the arc of circumference between two consecutive pressure rollers so that the tubular element 11 is always pinched by at least one roller 9a. This tubular element 11 is connected by its upstream end to the suction tube 12 and by its downstream end to the circuit 13 for supplying the nozzle 6. Preferably, the stator body 8a of the pump 8 is in the form of a hoop and is articulated by one of its ends to a support plate 7a, fixed to the lower wall of the shell 4. By its other end, the stator body 8a cooperates with at least one elastic member 17. Under the effect of the action of this elastic member, the stator 8a is held in position around the rotor 9. Preferably, this other end is provided with at least one through hole in which is engaged a threaded rod 18 secured to the support plate 7a. At the free end, this threaded rod 18 receives in screwing an adjusting and holding nut 19. The elastic member 17, constituted by a coil spring, is mounted on this threaded rod between the stator body 8a and the nut 19 Preferably two threaded rods 18, two springs 17 and two nuts will be provided. By screwing the nuts 19 more or less, it is possible to adjust the pressure force of the rollers 9a on the tubular element 11 of the pump 7. moreover, by removing the nuts 19, it becomes possible to angularly separate the stator body, for example with a view to removing or placing the tubular element 11. This tubular element 11, preferably made of synthetic material flexible, is positioned on the surface 8b and is engaged in two through holes made in the body of the stator 8a respectively upstream and downstream of said surface 8b. It should be noted that the plate 7a and the bearings 2b supporting the axle 2a are fixed relative to each other. In the case where a collapse of the wall of the shell supporting the plate 7a is to be feared, a reinforcing element may be disposed between this wall and the bearings 2b, this reinforcing element possibly, for example taking the form of an arch fixed on the one hand to said wall and on the other hand to the stirrups supporting the bearings 2b. According to an advantageous arrangement of the invention, the rotor 9 of the pump 7 comprises a smooth bearing 9b by which it is engaged on the axle 2a and a flange 9c fixed to this smooth bearing, this flange carrying on the one hand the rollers 9a, and on the other hand in an articulated manner, the pawl 10a of the pawl mechanism 10. The rollers 9a are mounted in free rotation and fixed in translation on axes fixed cantilevered on the flange 9c of the rotor 9. The rollers 9a and the axes which support them are parallel to the axle 2a as well as to the bearing surface 8b of the stator body 8. These rollers 9a are regularly away from each other. Preferably, the rotor 9 has at least three rollers 9a. The pawl 10a is mounted on a pin fixed cantilevered on the flange of the rotor 9. The pawl 10a is designed to cooperate in shape engagement with notches 10b formed in the axle 2a. The pawl 10a is returned to the engagement position in the notches 10b by an elastic member 10c such as a coil spring fixed on the one hand to said pawl and on the other hand to the flange 9c of the rotor 9. The supply circuit 13 in painting, comprises upstream of the valve 14 a pressure regulator 21 comprising an inlet in communication relation with the tubular element 11 by means of a filter 22, a first paint outlet in communication relation with the valve 14 and a second paint outlet in communication relation with the reservoir via a return line 21a. This return line 21a has a paint delivery orifice disposed as close as possible to the bottom of the hinge tank. When the value of the pressure in the regulator 21 becomes equal to or greater than the setting value of the latter, the second output of the pressure regulator 21, from a normally closed state, changes to an open state so that the liquid discharged by the pump 7 can return to the reservoir 5, the communication between the inlet of the regulator and the first outlet being always ensured. 'Thus, the machine can move forward, without the need to offload the pump by spraying. As in this case, the pump 7 sheds water in the tank 5 and simultaneously sucks the liquid paint contained in the latter, in this way, before spraying, automatic mixing of the paint in the tank 5 and a homogeneous mixture of different constituents of paint. During spraying, if the pressure in regulator 21 becomes equal to or greater than the setting value, the second outlet will go into the open state and part of the paint flow will return to the tank and the other part of the flow will feed the nozzle 6. Advantageously, downstream of the first outlet of the regulator 21 and upstream of the valve 14, the supply circuit 13 is associated with a sealed capacity 23 filled with air constituting an expansion vessel. This capacity 23 is pressurized by the pressure rise in the supply circuit under the effect of the pump flow. Thanks to this capacity 23, the supply circuit 13 of the nozzle 6, for its part upstream of the valve 14, is always kept under pressure so that the spraying begins as soon as the valve 14 is open. The energy reserve constituted by this capacity 23 thus authorizes a spraying, the pump 7 stopped. This technical characteristic, combined with the fact that the spray nozzle 6 and the downstream part of the valve 14 of the supply circuit are not fixed to the structure of the machine but simply positioned in a removable manner on this structure which gives them latitude. displacement relative to the machine, gives said machine great flexibility of use. Thus the user, after having grasped the spray nozzle, will be able to trace by hand or else trace with a stencil, a point characteristic of the surface to be painted. Regarding the marking of the marks of a sports field for example a football field, the tracing of straight lines or large curved lines will be operated by moving the machine on the ground and keeping the tap open, the nozzle being in place on the structure. On the other hand, the tracing of the lines of corner and penalty points, will be operated with the machine stopped, by the user. The part of the supply circuit, downstream from the tap 13 will be constituted by a flexible plastic tube of sufficient length to carry out these tracings by hand. As an example, this length will be of the order of 1.50 meters to 2 meters. Preferably, the capacity 23 is constituted by a tubular element, wound on itself according to one or more vertical loops fixed to the machine. The lower end of this tubular element is connected to the supply circuit 13 by a T-connector. The upper end of the tubular element is located above the vertical loop (s) formed and receives a pressure gauge 24. This upper end is preferably arranged at a height level greater than maximum level of paint in the tank so that the pressure gauge 24 is always disposed above this level. As a purely indicative example, to form the capacity 23, a tube with an internal diameter of about 8 millimeters and a length of 2 meters will be used. These vertical loops are positioned relative to the machine so that their winding axis is horizontal and parallel to the advancement axis of the machine. Because of this arrangement, the loops, when the machine is lying on the side remain vertical which avoids any backflow of paint towards the pressure gauge 24, the paint being trapped in the lower part of the vertical loop (s). The fact of producing the capacity 23 using a tubular element for example made of flexible synthetic material, while on the machine of the prior art is used an expansion vessel, allows a notable decrease in the cost of production of the machine, and the maintenance cost of the latter. Thanks to the manometer 24, which permanently indicates the pressure in the supply circuit 13, it is possible to adjust the setting value of the pressure regulator 21, the latter comprising adjustment means for this purpose. Preferably, the pressure gauge 24 will be mounted on a plate fixed to the handle 20 for maneuvering and as close as possible to the shape of the handle 20b that the latter comprises, so that it can be easily read by the user. The loops formed by the tubular element 23 will advantageously be arranged in the shell 4 of the machine, in a chamber that the latter comprises at the rear. According to a preferred embodiment, the operating mechanism 15 comprises a handle 15a, of the ambidextrous type, articulated to the operating handle 20, a 'cable 15b in sheath, fixed on the one hand to the handle 15a and on the other part to a maneuvering lever 14a which has the tap 14 and an elastic member 15c fixed on the one hand to the lever 14a of the maneuvering valve 14 and on the other hand to the rigid shell 4, this elastic member urging the maneuvering lever 14a in the direction of closing the valve 14. Preferably, the operating handle 15a is in the form of a hoop and has two end journals by which it is engaged in articulation on the one hand in a radial hole made in one of the lateral segments 20a of the handle 20 and on the other hand in a radial hole made in the other lateral segment of the handle, this handle 15a extending from one lateral segment to the other. To the operating handle 15a is fixed a plate. To this plate is fixed 30 the corresponding end of the cable 15b. By maneuvering the handle 15a towards the basal segment 20b of the maneuvering handle 20, a pulling force is printed on the cable 15b which is communicated to the maneuvering lever 14a of the tap 14. Under the effect of this force, the lever maneuver 14a is moved against the action of the elastic return member 15c from a position corresponding to the closing of the valve 14 to a position corresponding to the opening of the latter to authorize the supply of the nozzle 6 in painting and consequently spraying. This spraying is normally carried out when the machine is pushed forward by the user, but it can also be carried out when the machine is stopped as long as the air contained in the tank 23 is at sufficient pressure. It is understood that during this spraying when stopped, the air contained in the capacity 23 gradually relaxes. It should be noted that during spraying, the machine being running at normal speed, the pressure drop at the nozzle on the one hand and the pressure of the liquid delivered by the pump on the other are sufficient to ensure the rise of liquid in the capacity which compresses the air contained in the latter. The capacity thus constitutes a reserve of energy and absorbs to some extent the variations in pressure due for example to variations in the speed of the machine. Spraying occurs as long as the handle 15a is held by the user against the basal segment 20b of the operating handle. As soon as the user releases the handle 15a, the elastic member 15c returns the tap to the closed position by action on the lever 14a. The cable 15b is then pulled by the lever 14a which brings the handle 15a back to the initial position. To keep the reserve 23 under pressure for more or less long periods of machine stoppage, it is useful to avoid any risk of liquid reflux to the reservoir via the tube 11 of the pump and the suction tube 12 This reflux can result from wear of the rollers 9a or of the tube 11, such that the pinching of the tube by each roller is no longer carried out correctly and allows the liquid to pass through the pinched area. For this purpose, a non-return element 39 is arranged on the liquid path, upstream from the point of connection of the capacity 23 to the circuit 13. This non-return element may be constituted by a non-return valve. Preferably, for the sake of simplification, this non-return valve 39 is arranged on the suction tube 12 as can be seen in FIGS. 1 and 2. In these figures, it is noted that the non-return valve 39 is disposed at a distance from the suction orifice that the suction tube comprises, but this non-return valve can be mounted in said orifice or in a strainer associated with the latter. This arrangement avoids the emptying of the part of the tube immersed in the tank. The spray nozzle 6 is offset laterally with respect to the machine so that the marking carried out cannot be degraded by the passage of the wheels or by the steps of the user. Advantageously, the spray nozzle 6 will produce two jets of paint, one of which will be directed towards the front of the machine and the other towards the rear. Being a spray on a grassed surface, this arrangement allows the paint to be applied to the anterior and posterior faces of the blades of grass in a single pass. Preferably, the nozzle 6 is removably engaged in a vertical sleeve 31 open at both ends, carried by a horizontal support 26 secured to a support structure 30 fixed to the shell 4 of the machine. This horizontal support is transverse to the direction of advance of the machine. Preferably, the nozzle 6 is provided with a suspension hook 6a by which it is suspended from the vertical sleeve 31. Advantageously this vertical sleeve 31 is mounted in an adjustable manner in height on the transverse support 26. This arrangement makes it possible to adjust the height of the nozzle 6 with respect to the ground and consequently the width of the line drawn, the jet at the outlet of the nozzle being flat and triangular. To adjust the lateral offset of the nozzle relative to the machine, the position of the vertical sleeve 31 along the transverse support 26 will be adjustable. Preferably, on either side of the nozzle 6 and its support sleeve 31 will be installed in attachment to the transverse support 26, two vertical screens 28, in the form of rectangular or triangular walls, subject to come by their lower horizontal edge at most close to the ground. These screens 28 constitute an obstacle to the wind, and have the aim in particular of protecting the paint spray from the action of the latter. Preferably, the machine is provided with a pallet 28 disposed in front of the nozzle 6, said pallet comprising a lower lip subject to come into contact with the surface to be painted with a view to cleaning it by sweeping and essentially driving out the dew. According to a preferred embodiment, the transverse support 26, laterally to the sheath 31, is fixed a second horizontal support 32 in the form of a rigid bar, extending parallel to the direction of advance of the machine. By its distal end, this support 32 carries in front of the nozzle 6, by means of a elastic link 33, the pallet 34. This pallet 34 will advantageously be made of an elastically deformable synthetic material. Preferably, to give the pallet, in addition to the sweeping effect, a flushing effect, the latter is arranged obliquely relative to the direction of advance of the machine. The elastic connection 33 is advantageously constituted by a coil spring with contiguous turns, fixed on the one hand to the distal end of the horizontal support 32 and on the other hand to the pallet 34. Thanks to this elastic connection arrangement 33, the pallet 34, when it encounters an obstacle, which can for example be a goal post, can easily be erased in front of the obstacle, by deformation of the elastic connection. It therefore becomes possible to carry out the marking up to the obstacle encountered. According to a first embodiment, the support structure 30 comprises a horizontal tube 35 fixed to the lower wall 4b of the shell 4, this tube comprising at the front end a vertical sleeve in which is engaged and locked, by a pressure screw, a nozzle vertical fixed to the transverse support 26. According to another embodiment, the support structure 30 always comprises the horizontal tube 35 fixed to the lower wall 4b of the shell 4, this tube always comprising at the front end a vertical sleeve " in which is engaged and blocked by a pressure screw, a vertical end piece no longer fixed to the transverse support 26, but to one of the two elements 37 of an articulation 36 with a horizontal axis and perpendicular to the direction of advance of the machine. element 38 of the articulation is arranged as a lever arm and receives at the distal end on the one hand the transverse support 26 and on the other hand a support member 27 on the ground which can be const ituted by a wheel, by a sliding pad or other. The advantage of such an arrangement lies in the fact that the nozzle 6 can follow the irregularities of the ground so that the width of the line formed will be uniform. The machine will also be equipped with a water tank 25 for cleaning the pump, the supply circuit and the spray nozzle 6. To clean the suction tube 12 will be immersed in the tank 25 and the machine will be driven forward. This cleaning can perfectly be carried out immediately after tracing, in particular during the journey of return of the machine to the technical room. For this cleaning, the valve 14 is opened by action on the handle 15a. The cleaning water should be collected. For this purpose the nozzle 6 is immersed in the paint tank or else in the water tank. The machine as described is mainly intended for marking sports fields with or without grass, but it goes without saying that it can be used for the formation of marks on any other type of surface, for example on traffic lanes and the like. We have previously described a machine having only one spray nozzle 6, but it goes without saying that this machine can be equipped with several nozzles 6 connected for example to the same supply circuit 13 and mounted for example on the same support transverse 26. Similarly, the use of the machine is not limited to spraying a paint, so the machine can be used for spraying surface treatment liquids such as weed killers, fertilizers, etc. It goes without saying that the present invention can receive all arrangements and variants in the field of technical equivalences without departing from the scope of this patent.
