Abstract

The device has a chassis (1) on wheels (2). The chassis supports a pump (3) with a suction (4) and outlet (5) ferrules. The outlet ferrule is connected through an outlet pipe (6) to a distribution nozzle (7). The chassis supports a paint container (9) having a neck (49). The pump suction ferrule is connected to a suction pipe (10) having a flexible part (46) introduced into the container through its neck. The suction pipe has a plug (11) fitting into the container neck. The plug rim external diameter is greater than that of the container neck so that the plug abuts on the neck. A central passage through the plug provides atmospheric pressure inside the container. The plug has a cylindrical body in which is inserted a channel, parallel to the plug longitudinal axis, whose axial length is greater than that of the plug. Thus its ends pass through the plug and constitute ferrule connections for the suction pipe. The pump outlet chamber has an outlet (56) connected to a return pipe (57) passing through the plug.

Description

La présente invention concerne les appareils à tracer des lignes au sol. Certains de ces appareils sont constitués d'un châssis monté sur roues, lequel châssis supporte une pompe munie d'un embout d'aspiration et d'un embout de refoulement ; l'embout de refoulement est relié par une canalisation de refoulement à une buse de distribution distribuant une peinture pour la réalisation des lignes au sol, telles que les lignes délimitant des terrains de jeu par exemple ; pour son application, la peinture est versée depuis un conteneur, tel qu'un bidon, dans lequel elle est commercialisée, dans un réservoir solidaire du châssis de l'appareil, la canalisation d'aspiration, le plus souvent rigide, étant par ailleurs reliée à la partie basse du réservoir.The present invention relates to apparatus for drawing lines on the ground. Some of these devices consist of a chassis mounted on wheels, which chassis supports a pump provided with a suction nozzle and a discharge nozzle; the discharge end piece is connected by a discharge line to a distribution nozzle distributing a paint for the production of lines on the ground, such as the lines delimiting playgrounds for example; for its application, the paint is poured from a container, such as a can, in which it is sold, in a tank integral with the chassis of the apparatus, the suction pipe, most often rigid, being also connected at the bottom of the tank.

Une telle disposition, selon laquelle le réservoir fait partie intégrante de l'appareil, présente des inconvénients : la mise en oeuvre n'est pas facilitée par la nécessité d'alimenter le réservoir en peinture en la transvasant depuis son conteneur ; de plus, le vidage et le nettoyage ne sont pas aisés.Such an arrangement, according to which the reservoir forms an integral part of the apparatus, has drawbacks: the implementation is not facilitated by the need to supply the reservoir with paint by transferring it from its container; moreover, emptying and cleaning are not easy.

US-A-4 624 602 décrit un appareil à tracer des lignes au sol par application d'une peinture, ledit appareil étant constitué d'un châssis monté sur roues, ledit châssis supportant une pompe munie d'un embout d'aspiration et d'un embout de refoulement, ledit embout de refoulement étant relié par une canalisation de refoulement à une buse de distribution ; rien n'est prévu dans ce document pour faciliter l'entretien de l'appareil, et la peinture que l'appareil est amené à pulvériser sous pression est contenue dans un seau ou dans un réservoir et aucune précision n'est donnée concernant ce récipient.US-A-4,624,602 describes an apparatus for drawing lines on the ground by applying a paint, said apparatus consisting of a chassis mounted on wheels, said chassis supporting a pump provided with a suction nozzle and d 'a discharge nozzle, said discharge nozzle being connected by a discharge pipe to a dispensing nozzle; nothing is provided in this document to facilitate the maintenance of the device, and the paint that the device is required to spray under pressure is contained in a bucket or a tank and no details are given concerning this container. .

US-A- 5 213 480 décrit également un appareil à tracer des lignes dont l'ensemble moto-pompe est déplaçable verticalement pour faciliter le changement du conteneur à peinture ; celui-ci, représenté en traits mixtes, présente un large couvercle spécifique à fente pour le passage des organes d'aspiration de la pompe ; les terrains de sports, sur lesquels l'appareil est amené à tracer des lignes, n'étant pas toujours rigoureusement plans, un tel couvercle peut entraîner un débordement important de peinture, celle-ci étant du type fluide.US-A-5,213,480 also describes an apparatus for drawing lines in which the motor-pump assembly is vertically movable to facilitate the change of the paint container; the latter, shown in dashed lines, has a large specific slit cover for the passage of the suction members of the pump; sports fields, on which the device is required to draw lines, not always being strictly planar, such a cover can cause a significant overflow of paint, the latter being of the fluid type.

L'invention a pour but de pallier ces inconvénients et pour objet un appareil à tracer dont la mise en oeuvre et l'entretien sont simples, faciles, rapides, avec un minimum de manipulations et manutentions, et permettant de tracer des lignes sans débordement de peinture même sur un terrain non rigoureusement plan.The invention aims to overcome these drawbacks and relates to a drawing device whose implementation and maintenance are simple, easy, fast, with a minimum of handling and handling, and for drawing lines without overflow of painting even on ground that is not strictly level.

Avantageusement, la canalisation d'aspiration porte un bouchon qu'elle traverse et qui est adapté à coopérer avec le goulot du conteneur ; le bouchon présente un rebord dont le diamètre externe est plus grand que celui du goulot du conteneur de sorte que le bouchon est adapté à venir en butée sur ledit goulot par l'intermédiaire dudit rebord.Advantageously, the suction pipe carries a plug which it passes through and which is adapted to cooperate with the neck of the container; the stopper has a rim whose outer diameter is larger than that of the neck of the container so that the stopper is adapted to come into abutment on said neck through said rim.

De préférence, le bouchon est traversé par un passage central pour la mise à l'atmosphère de l'intérieur du conteneur.Preferably, the cap is crossed by a central passage for venting the interior of the container.

Avantageusement, le bouchon comprend un corps de forme générale cylindrique dans lequel a été inséré un canal disposé parallèlement à l'axe longitudinal du bouchon et dont la longueur axiale est supérieure à celle du bouchon en sorte que ses extrémités dépassent axialement du bouchon pour constituer des embouts de raccordement auxquels est raccordée la canalisation d'aspiration.Advantageously, the plug comprises a body of generally cylindrical shape into which has been inserted a channel arranged parallel to the longitudinal axis of the plug and whose axial length is greater than that of the plug so that its ends protrude axially from the plug to form connection fittings to which the suction pipe is connected.

De préférence, la chambre de refoulement de la pompe présente une sortie reliée à une canalisation de retour traversant également le bouchon ; dans le corps a été inséré un canal disposé parallèlement à l'axe longitudinal du bouchon et dont la longueur axiale est supérieure à celle du bouchon en sorte que ses extrémités dépassent axialement du bouchon pour constituer des embouts de raccordement auxquels est raccordée la canalisation dde retour. Avantageusement, les canaux sont métalliques et ont été insérés par surmoulage ou montage à force.Preferably, the discharge chamber of the pump has an outlet connected to a return pipe also passing through the plug; in the body has been inserted a channel arranged parallel to the longitudinal axis of the plug and whose axial length is greater than that of the plug so that its ends protrude axially from the plug to form connection nipples to which the return pipe is connected . Advantageously, the channels are metallic and have been inserted by overmolding or force fitting.

De préférence, le bouchon est en matière moulée d'une seule pièce.Preferably, the plug is made from a single piece of molded material.

Avantageusement, le débit de peinture à travers la buse de distribution est réglable.Advantageously, the paint flow rate through the dispensing nozzle is adjustable.

De préférence, la buse de distribution est portée par un organe de support monté de manière amovible sur un tube support porté par l'appareil.Preferably, the dispensing nozzle is carried by a support member removably mounted on a support tube carried by the device.

Avantageusement, la pompe est entraînée électriquement à partir d'une batterie placée dans un bac porté par l'appareil.Advantageously, the pump is electrically driven from a battery placed in a tank carried by the device.

Le manchon 36 est solidaire de la douille 38 d'un pare-vent 40 par l'intermédiaire d'une entretoise 39.At the front of the tank 23, the longitudinal beam 12 carries a vertical post 35; on this upright 35 is slidably mounted a sleeve 36 whose height position on the upright 35 is adjustable and maintained by a screw 37. The sleeve 36 is integral with the sleeve 38 of a wind screen 40 by means of a spacer 39.

Comme cela est visible sur les dessins, l'entretoise 39 est inclinée par rapport à l'axe longitudinal de l'appareil en sorte que la douille 38 du pare-vent 40 est située pratiquement dans le plan médian longitudinal vertical de l'appareil, c'est-à-dire dans le plan vertical qui contient le support de guidon 15; ce même plan contient également une mire verticale 41 portée à l'avant par le pare-vent 40, ce qui facilite la mise en oeuvre de l'appareil à tracer.As can be seen in the drawings, the spacer 39 is inclined relative to the longitudinal axis of the device so that the sleeve 38 of the wind screen 40 is situated practically in the vertical longitudinal median plane of the device, that is to say in the vertical plane which contains the handlebar support 15; this same plane also contains a vertical sight 41 carried at the front by the wind screen 40, which facilitates the implementation of the apparatus to be traced.

A l'intérieur de la douille 38 est monté coulissant un tube-support 42 dont la position en hauteur est réglable et maintenue par une vis 43 ; le tube 34 qui porte la buse 7 est solidarisé à l'intérieur d'un organe de support 61 placé dans le tube-support 42 ; il présente à sa partie supérieure une collerette 44 par laquelle il vient en butée sur le bord supérieur du tube-support 42.Inside the bush 38 is slidably mounted a support tube 42 whose height position is adjustable and maintained by a screw 43; the tube 34 which carries the nozzle 7 is secured inside a support member 61 placed in the support tube 42; it has at its upper part a flange 44 by which it abuts on the upper edge of the support tube 42.

Le robinet 32 et la vanne 33 sont avantageusement supportés par l'entretoise 39.The tap 32 and the valve 33 are advantageously supported by the spacer 39.

Le tronçon de la canalisation de refoulement 6 compris entre la vanne 33 et le tube 34, qui porte la buse 7, est souple, ceci facilitant la mise en place du tube 34, donc de la buse 7, dans le tube support 42, ainsi que son retrait. Les autres tronçons de la canalisation de refoulement 6, l'un compris entre le robinet 32 et l'amortisseur 31, l'autre compris entre ledit amortisseur 31 et l'embout de refoulement 5 de la pompe 3 sont également prévus souples selon l'exemple représenté mais bien entendu ces deux tronçons pourraient être du type rigide.The section of the discharge line 6 between the valve 33 and the tube 34, which carries the nozzle 7, is flexible, this facilitating the positioning of the tube 34, therefore of the nozzle 7, in the support tube 42, thus that his withdrawal. The other sections of the discharge line 6, one between the valve 32 and the damper 31, the other between said damper 31 and the discharge end 5 of the pump 3 are also provided flexible according to the example shown, but of course these two sections could be of the rigid type.

La pompe 3 comporte un embout d'aspiration 4 auquel est reliée une extrémité d'une canalisation d'aspiration 10 sur laquelle est placé un filtre 45 fixé au châssis 1, ici sur une bretelle latérale 22 reliant les étriers 18 et 19 du berceau constituant les moyens de réception 8.The pump 3 includes a suction nozzle 4 to which is connected one end of a suction pipe 10 on which is placed a filter 45 fixed to the frame 1, here on a side strap 22 connecting the stirrups 18 and 19 of the cradle constituting the reception means 8.

La canalisation d'aspiration 10 porte un dispositif 11, désigné par le bouchon 11 dont le rôle apparaîtra ci-après.The suction line 10 carries a device 11, designated by the plug 11, the role of which will appear below.

Le tronçon 46 de la canalisation d'aspiration 10 compris entre le filtre 45 et le bouchon 11 est un tronçon souple ; dans l'exemple représenté le tronçon compris entre le filtre 45 et l'embout d'aspiration 4 de la pompe 3 est également souple mais bien entendu il pourrait être rigide.The section 46 of the suction line 10 between the filter 45 and the plug 11 is a flexible section; in the example shown the section between the filter 45 and the suction nozzle 4 of the pump 3 is also flexible but of course it could be rigid.

Plus précisément, en se reportant également aux figures 6 et 7, le bouchon 11 comprend un corps 47 de forme générale cylindrique, à section circulaire, avantageusement en matière plastique ou caoutchouteuse, dans lequel ont été insérés, par surmoulage ou montage à force, deux canaux 50, 51 métalliques disposés parallèlement à l'axe longitudinal du bouchon 11, dont la longueur axiale est supérieure à celle du bouchon 11 en sorte que leurs extrémités dépassent axialement du bouchon 11 pour constituer des embouts de raccordement ; ainsi, chaque canal 50, 51 définit un passage axial à travers le bouchon 11, respectivement 52, 53.More specifically, with reference also to FIGS. 6 and 7, the plug 11 comprises a body 47 of generally cylindrical shape, of circular section, advantageously made of plastic or rubbery material, into which have been inserted, by overmolding or force fitting, two metal channels 50, 51 arranged parallel to the longitudinal axis of the plug 11, the axial length of which is greater than that of the plug 11 so that their ends protrude axially from the plug 11 to form connection end pieces; thus, each channel 50, 51 defines an axial passage through the plug 11, respectively 52, 53.

Par ailleurs, le corps 47 du bouchon 11 est traversé par un passage central 54.Furthermore, the body 47 of the plug 11 is crossed by a central passage 54.

A sa partie supérieure, le corps 47 présente un rebord circulaire 55 s'étendant radialement au-delà de la surface cylindrique externe du corps 47.At its upper part, the body 47 has a circular rim 55 extending radially beyond the external cylindrical surface of the body 47.

Le tronçon 46 de la canalisation d'aspiration 10 est raccordé à la partie supérieure du canal 50 dont la partie inférieure porte un tronçon 48 d'aspiration proprement dite à extrémité libre avantageusement biseautée.The section 46 of the suction pipe 10 is connected to the upper part of the channel 50, the lower part of which carries a suction section 48 with a free end advantageously bevelled.

La chambre de refoulement de la pompe 3 présente une sortie 56 autre que celle constituée par l'embout de refoulement 5 ; cette sortie 56 est reliée par une canalisation 57 dite de retour à la partie supérieure du canal 51 du bouchon 11, canal 51 dont la partie inférieure porte un tronçon de retour 58, de longueur inférieure à celle du tronçon d'aspiration 48.The discharge chamber of the pump 3 has an outlet 56 other than that constituted by the discharge nozzle 5; this outlet 56 is connected by a pipe 57 known as the return pipe to the upper part of the channel 51 of the plug 11, channel 51, the lower part of which carries a return section 58, of length less than that of the suction section 48.

Sur la canalisation de retour 57, est prévu un organe de réglage 59, du genre robinet à pointeau, permettant de régler le débit à travers la canalisation de retour 57 ; l'organe de réglage 59 est solidarisé au châssis 1 et porte lui-même un manomètre 60, visible sur la figure 2, indiquant la pression de refoulement de la pompe 3 en fonctionnement.On the return pipe 57, an adjusting member 59 is provided, of the needle valve type, making it possible to adjust the flow rate through the return pipe 57; the adjusting member 59 is secured to the chassis 1 and itself carries a pressure gauge 60, visible in FIG. 2, indicating the discharge pressure of the pump 3 in operation.

Le tronçon de la canalisation de retour 57 compris entre l'organe de réglage 59 et le bouchon 11 est prévu souple ; le tronçon de cette canalisation de retour 57 compris entre l'organe de réglage 59 et la pompe 3 est souple également, selon l'exemple représenté, mais pourrait être rigide.The section of the return pipe 57 included between the adjusting member 59 and the plug 11 is provided flexible; the section of this return pipe 57 between the adjusting member 59 and the pump 3 is also flexible, according to the example shown, but could be rigid.

La mise en oeuvre et le fonctionnement de l'appareil sont les suivants.The implementation and operation of the device are as follows.

Lorsque l'utilisateur désire tracer des lignes au sol avec l'appareil selon l'invention, il prend un conteneur ou bidon 9 dans lequel une peinture prête à l'emploi est commercialisée et place ce conteneur 9 dans le berceau constituant les moyens de réception 8 de l'appareil ; ces moyens sont agencés pour recevoir un conteneur 9 contenant par exemple vingt litres de peinture prête à l'emploi, ce qui est la taille la plus couramment utilisée.When the user wishes to draw lines on the ground with the apparatus according to the invention, he takes a container or can 9 in which a ready-to-use paint is sold and places this container 9 in the cradle constituting the receiving means 8 of the apparatus; these means are arranged to receive a container 9 containing for example twenty liters of ready-to-use paint, which is the most commonly used size.

Après avoir ôté l'obturateur fermant le goulot 49 du conteneur 9, l'utilisateur plonge dans le conteneur 9, à travers le goulot 49, les tronçons d'aspiration 48 et de retour 58 jusqu'à ce que le rebord circulaire 55 du bouchon 11, porté par les canalisations d'aspirations 10 et de retour 57, repose sur le bord supérieur du goulot 49 du conteneur 9 ; dans cette position, comme le montre la figure 6, l'extrémité du tronçon d'aspiration 48 est pratiquement au contact du fond du récipient 9, celle du tronçon de retour 58 étant à distance de ce fond.After removing the shutter closing the neck 49 of the container 9, the user plunges into the container 9, through the neck 49, the suction 48 and return 58 sections until the circular flange 55 of the cap 11, carried by the suction and return pipes 57 and 57, rests on the upper edge of the neck 49 of the container 9; in this position, as shown in FIG. 6, the end of the suction section 48 is practically in contact with the bottom of the container 9, that of the return section 58 being at a distance from this bottom.

Grâce au passage central 54 ménagé à travers le bouchon 11, l'intérieur du conteneur 9 est en permanence à la pression atmosphérique, même si le bouchon 11 s'ajuste parfaitement à l'intérieur du goulot 49 ; on comprendra que cet ajustement n'est pas indispensable, le diamètre extérieur du bouchon 11 pouvant être inférieur au diamètre intérieur du goulot 49, pourvu que le rebord circulaire 55 du bouchon 11 ait un diamètre suffisant pour reposer sur le bord supérieur du goulot 49.Thanks to the central passage 54 formed through the plug 11, the interior of the container 9 is permanently at atmospheric pressure, even if the plug 11 fits perfectly inside the neck 49; it will be understood that this adjustment is not essential, the outside diameter of the plug 11 possibly being less than the inside diameter of the neck 49, provided that the circular rim 55 of the plug 11 has a diameter sufficient to rest on the upper edge of the neck 49.

Il suffit alors de vérifier que le robinet 32 est ouvert et de manoeuvrer l'interrupteur 28 pour mettre en route la pompe 3 et distribuer la peinture à travers la buse de distribution 7 dont le débit peut être réglé par la vanne 33 et/ou l'organe de réglage 59 qui fixe le débit de peinture à travers la canalisation de retour 57 ; il est à noter qu'un tel débit de retour permet d'agiter en permanence la peinture dans le conteneur 9 qui, dès lors, reste parfaitement homogène pendant l'application ; par ailleurs, cette agitation permanente permet également d'éviter les dépôts de peinture sur les parois et le fond du conteneur 9 : ces dépôts, lorsqu'il n'y a pas d'agitation permanente, sont en général constitués de particules de matières actives et la peinture distribuée, privée de ces particules, est moins pure, moins éclatante ; par ailleurs, ces dépôts augmentent la consommation de peinture et rendent le nettoyage plus difficile.It then suffices to check that the tap 32 is open and to operate the switch 28 to start the pump 3 and distribute the paint through the dispensing nozzle 7, the flow rate of which can be adjusted by the valve 33 and / or the 'adjusting member 59 which fixes the paint flow rate through the return line 57; it should be noted that such a return flow makes it possible to constantly stir the paint in the container 9 which, therefore, remains perfectly homogeneous during the application; moreover, this permanent agitation also makes it possible to avoid deposits of paint on the walls and the bottom of the container 9: these deposits, when there is no permanent agitation, generally consist of particles of active materials. and the distributed painting, deprived of these particles, is less pure, less brilliant; moreover, these deposits increase the consumption of paint and make cleaning more difficult.

La largeur du trait tracé est réglée également en modifiant la hauteur de la buse 7 par rapport au sol, grâce à la vis 43.The width of the drawn line is also adjusted by modifying the height of the nozzle 7 relative to the ground, using the screw 43.

Lorsque l'opération de traçage est terminée, il est aisé de nettoyer l'appareil : il suffit en effet de retirer le bouchon 11, grâce à la souplesse des canalisations qui le portent, et de plonger le tronçon d'aspiration 48 dans un récipient contenant un liquide nettoyant, généralement de l'eau compte tenu de la nature de la peinture utilisée pour le traçage de lignes au sol ; en plaçant le bouchon 11 au droit de la paroi dudit récipient, le tronçon d'aspiration 48 plongeant dans le liquide, le tronçon de retour 58 est à l'extérieur du récipient, au droit d'un caniveau par exemple ; la mise en route de la pompe 3 permet alors de façon simple un nettoyage rapide et complet de tous les organes de l'appareil ayant eu à véhiculer de la peinture. Par exemple, à capacité égale, lorsqu'un appareil de l'état antérieur nécessitait une demi-heure, voire trois quarts d'heure, de nettoyage, ici une à deux minutes suffisent. Par ailleurs, le conteneur 9 ayant été muni à nouveau de son organe de fermeture est, tel quel, prêt pour être stocké en attente de l'opération suivante.When the tracing operation is finished, it is easy to clean the device: it suffices to remove the plug 11, thanks to the flexibility of the pipes which carry it, and to immerse the suction section 48 in a container containing a cleaning liquid, generally water, taking into account the nature of the paint used for drawing lines on the ground; by placing the plug 11 in line with the wall of said container, the suction section 48 plunging into the liquid, the return section 58 is outside the container, in line with a gutter for example; starting pump 3 allows then in a simple manner rapid and complete cleaning of all the organs of the apparatus having had to convey paint. For example, at equal capacity, when a device of the previous state required half an hour, or even three quarters of an hour, cleaning, here one to two minutes is enough. Furthermore, the container 9 having been provided again with its closing member is, as it is, ready to be stored pending the next operation.

Bien entendu, l'appareil pourrait ne pas comporter de circuit de retour, auquel cas le bouchon 11 ne comporterait que le canal 50 et le passage central 54.Of course, the device could not include a return circuit, in which case the plug 11 would only include the channel 50 and the central passage 54.

La figure 8 montre une variante de bouchon 11 selon laquelle celui-ci est d'une seule pièce obtenue par moulage.Figure 8 shows a variant of plug 11 according to which it is in one piece obtained by molding.

Selon l'exemple décrit et représenté, la pompe 3 est entraînée électriquement à partir de la batterie 24 ; en variante, l'appareil comporte une pompe entraînée mécaniquement à partir des roues lorsque l'appareil est poussé pour le traçage.According to the example described and shown, the pump 3 is electrically driven from the battery 24; alternatively, the device comprises a pump driven mechanically from the wheels when the device is pushed for tracing.

Grâce à l'appareil selon l'invention, l'opération de traçage de lignes au sol nécessite un temps plus court que celui obtenu avec les appareils connus à ce jour ; le coût de l'opération de traçage, compte tenu en outre de la facilité avec laquelle l'appareil est nettoyé et entretenu, s'en trouve réduit également.Thanks to the device according to the invention, the operation of tracing lines on the ground requires a shorter time than that obtained with the devices known to date; the cost of the tracing operation, also taking into account the ease with which the device is cleaned and maintained, is also reduced.
