Description

La présente invention concerne un dispositif pour la pulvérisation d'un produit liquide, sur une zone ou une surface disposée à distance de l'utilisateur, telle que par exemple une toiture ou une façade d'une construction.The present invention relates to a device for spraying a liquid product, on an area or a surface disposed at a distance from the user, such as for example a roof or a facade of a construction.

La pulvérisation de liquide, sous forme de pluie ou de fines gouttelettes, est rendue nécessaire dans des applications diverses. Par exemple, il peut être nécessaire de répandre un liquide dans un jardin, une zone cultivée, pour répandre de l'engrais liquide, ou contraire dans une zone que l'on souhaite débarrasser de plantes, en épandant un désherbant. Dans un autre exemple d'application, le traitement des toitures et des façades d'habitations nécessite de vaporiser ou d'épandre un liquide spécifique pour le traitement, visant par exemple à enlever la mousse, les champignons, ou un produit de nettoyage.The spraying of liquid, in the form of rain or fine droplets, is made necessary in various applications. For example, it may be necessary to spread a liquid in a garden, a cultivated area, to spread liquid fertilizer, or otherwise in an area that is desired to rid of plants, by spreading a weed killer. In another example of application, the treatment of roofs and house facades requires spraying or spreading a specific liquid for the treatment, for example to remove the foam, fungi, or a cleaning product.

Cette opération de pulvérisation de liquide est usuellement réalisée à l'aide d'une buse, disposé à l'extrémité d'une perche rigide, tenue à la main par l'utilisateur. L'autre extrémité de la perche est reliée à un tuyau d'alimentation, lui-même relié à une réserve de liquide destiné au traitement. La réserve est généralement constituée d'une bonbonne ou d'un réservoir, disposé sur un véhicule roulant ou sur le dos de l'utilisateur.This liquid spraying operation is usually carried out using a nozzle, placed at the end of a rigid pole, held in the hand by the user. The other end of the pole is connected to a feed pipe, itself connected to a reserve of liquid for treatment. The reserve generally consists of a tank or a tank, arranged on a vehicle or on the back of the user.

Le rayon d'action est limité à la hauteur de l'utilisateur, allongé de la longueur de son bras, auquel on ajoute la longueur de la perche portant la buse de pulvérisation. Ainsi, la buse peut être disposée au grand maximum à 6 m du sol en hauteur.The radius of action is limited to the height of the user, extended length of his arm, which is added the length of the boom carrying the spray nozzle. Thus, the nozzle can be arranged at a maximum at 6 m from the ground in height.

Pour l'épandage de liquide sur le sol, cette technique ne soulève pas de difficultés particulières. En revanche, pour les zones situées en hauteur, telles que les façades, murs, et encore plus les toitures, la technique connue oblige l'utilisateur à utiliser des échafaudages, coûteux et présente des risques sur le plan de la sécurité.For the spreading of liquid on the ground, this technique does not raise particular difficulties. On the other hand, for the zones situated in height, such as facades, walls, and even more roofs, the known technique requires the user to use scaffolding, expensive and presents risks in terms of security.

On a proposé par le brevet FR 2 854 912 , au nom de l'un des demandeurs, de disposer la ou les buse(s) sur un ensemble de pulvérisation, accroché à un rail suspendu par l'intermédiaire de moyens de levage, tel qu'une grue. L'ensemble est télécommandé à distance et se déplace donc sur la toiture selon la ligne de pente, d'une part, et horizontalement par dépassement sur le rail, d'autre part.It has been proposed by the patent FR 2,854,912 , on behalf of one of the applicants, to arrange the nozzle (s) on a spray assembly, hooked to a suspended rail by means of lifting means, such as a crane. The set is remotely controlled remotely and therefore moves on the roof along the slope line, on the one hand, and horizontally by passing on the rail, on the other hand.

Ce dispositif connu permet de traiter (pour enlever la mousse) des toitures à distance, de grande hauteur et de grande surface. Cependant, il nécessite la présence de moyens de levage, qui peuvent se révéler onéreux, notamment pour les toitures de petites surfaces.This known device makes it possible to treat (to remove the foam) roofs at a distance, high height and large area. However, it requires the presence of lifting means, which can be expensive, especially for roofs of small areas.

Par ailleurs, le document DE 202 02 552 U1 décrit un dispositif pour la pulvérisation de liquide, à distance de l'utilisateur, du type comportant au moins une buse de pulvérisation disposée à une première extrémité d'une perche dont la seconde extrémité est tenue par l'utilisateur, la ou les buses étant reliées, par l'intermédiaire d'un conduit souple, à un réservoir de liquide à pulvériser, comportant un chariot sur lequel est fixée la ou les buses, le chariot étant pourvu de moyens de déplacement orientables, et comportant des moyens de manoeuvre de l'orientation des moyens de déplacement formés d'au moins un jeu de deux roues ou galets, les moyens de manoeuvre étant actionnables à distance par l'utilisateur depuis la seconde extrémité de la perche par où celui-ci tient la perche, par pivotement de la seconde extrémité de la perche.In addition, the document DE 202 02 552 U1 describes a device for spraying liquid, at a distance from the user, of the type comprising at least one spray nozzle disposed at a first end of a pole whose second end is held by the user, the nozzle or nozzles being connected, via a flexible conduit, to a spray liquid tank, comprising a carriage on which is fixed the nozzle or nozzles, the carriage being provided with steerable displacement means, and comprising means for operating the nozzle; orientation of the displacement means formed of at least one set of two wheels or rollers, the actuating means being operable remotely by the user from the second end of the pole through which the latter holds the pole, by pivoting the second end of the pole.

La présente invention a pour objectif de remédier à ces inconvénients, et propose un dispositif pour la pulvérisation du liquide, à distance de l'utilisateur, qui soit commode d'utilisation, léger, tout en permettant de s'adapter à des situations différentes, telles que par exemple de grandes hauteurs de façade, ou des toitures élevées, et le tout dans des conditions de sécurité optimales.The present invention aims to overcome these disadvantages, and proposes a device for spraying the liquid, at a distance of the user, which is convenient to use, lightweight, while allowing to adapt to different situations, such as for example large facade heights, or high roofs, and all in conditions of optimum safety.

À cet fin, selon invention, le dispositif pour la pulvérisation de liquide, à distance de l'utilisateur, du type comportant au moins une buse de pulvérisation disposée à une première extrémité d'une perche dont la seconde extrémité est tenue par l'utilisateur, la ou les buses étant reliées, par l'intermédiaire d'un conduit souple, à un réservoir de liquide à pulvériser, est caractérisé en ce qu'il comporte un chariot sur lequel est fixée la ou les buses, le chariot étant pourvu de moyens de déplacement orientables et en ce qu'il comporte des moyens de manoeuvre de l'orientation des moyens de déplacement, les moyens de manoeuvre étant actionnables à distance par l'utilisateur.To this end, according to the invention, the device for spraying liquid, remote from the user, of the type comprising at least one spray nozzle disposed at a first end of a pole whose second end is held by the user. , the nozzle or nozzles being connected, via a flexible conduit, to a spray liquid tank, is characterized in that it comprises a carriage on which is fixed the nozzle or nozzles, the carriage being provided with orientable moving means and in that it comprises means for actuating the orientation of the displacement means, the operating means being remotely operable by the user.

On entend par déplacement orientable, un déplacement avec une orientation variable par rapport à un axe transversal vertical.Orientable displacement means a displacement with a variable orientation relative to a vertical transverse axis.

Les moyens de déplacement sont formés d'au moins un jeu de deux roues ou galets, ou d'un jeu de deux chenilles.The displacement means are formed of at least one set of two wheels or rollers, or a set of two tracks.

Les moyens de manoeuvre de l'orientation des roues sont actionnables par l'utilisateur depuis la seconde extrémité de la perche par où celui-ci tient la perche. De préférence, ils sont actionnables mécaniquement, en particulier par pivotement de la seconde extrémité de la perche.The wheel orientation of the maneuvering means are operable by the user from the second end of the pole through which it holds the pole. Preferably, they are operable mechanically, in particular by pivoting the second end of the pole.

Ainsi, le dispositif de l'invention peut être manoeuvré et tenu sans effort par l'utilisateur, puisque ce dernier tient la seconde extrémité de la perche d'une main, tandis que la première extrémité de la perche (portant la buse) repose et se déplace sur la surface à traiter.Thus, the device of the invention can be maneuvered and held effortlessly by the user, since the latter holds the second end of the pole with one hand, while the first end of the pole (carrying the nozzle) rests and moves on the surface to be treated.

De plus, le dispositif est aisé à orienter et diriger en pilotant les roues du chariot à distance, pour réaliser un épandage ad hoc, par la buse, ce qui permet de traiter avec efficacité la zone à traiter, que ce soit pour ravaler une façade en hauteur, ou une toiture, à distance de l'utilisateur, en particulier au-delà de 2 à 3 mètres.In addition, the device is easy to orient and direct by driving the wheels of the carriage at a distance, to achieve an ad hoc spreading by the nozzle, which allows to effectively treat the area to be treated, whether to swallow a facade in height, or a roof, away from the user, especially beyond 2 to 3 meters.

Selon une caractéristique, le dispositif comporte un support central sur lequel est fixée, d'une part la première extrémité de la perche et d'autre part les moyens de déplacement (roues ou chenilles). Ce support constitue le barycentre du chariot.According to one characteristic, the device comprises a central support on which is fixed on the one hand the first end of the pole and on the other hand the displacement means (wheels or tracks). This support is the center of gravity of the cart.

Selon un mode préféré de réalisation, les moyens de manoeuvre de l'orientation des roues, sont du type mécanique ou électromécanique. De préférence, les moyens de manoeuvre incluent un système de transmission, tels que des engrenages, reliant la première extrémité de la perche audit chariot. Ce type de moyen de transmission, notamment à engrenages, permet de manoeuvrer à distance mécaniquement les roues (par pivotement de la perche reliée au système de transmission), de manière simple et peu onéreuse, au lieu d'un pilotage électronique à distance.According to a preferred embodiment, the means for actuating the orientation of the wheels are of the mechanical or electromechanical type. Preferably, the operating means include a transmission system, such as gears, connecting the first end of the pole to said carriage. This type of transmission means, in particular with gears, makes it possible to mechanically maneuver the wheels (by pivoting the boom connected to the transmission system) in a simple and inexpensive manner, instead of remote electronic control.

D'autres systèmes de déplacement du chariot et manoeuvre des moyens de déplacement peuvent bien entendu être envisagés.Other carriage displacement systems and maneuvering means of displacement can of course be considered.

De préférence, les roues orientables sont disposées à chaque extrémité d'un essieu commun sur lequel est fixée la buse de pulvérisation, l'essieu étant relié à l'extrémité de la perche, par ledit système de transmission. Ce dernier comporte avantageusement un premier pignon solidaire de l'essieu, qui prend prise avec un second pignon solidaire de l'extrémité de la perche.Preferably, the steerable wheels are disposed at each end of a common axle on which is fixed the spray nozzle, the axle being connected to the end of the pole, by said transmission system. This last advantageously comprises a first pinion integral with the axle, which engages with a second pinion integral with the end of the pole.

Avantageusement, le dispositif comporte une rampe pourvue d'au moins une buse (de préférence deux buses), dont l'extrémité distale est fixée, par l'intermédiaire du support, sur le système de transmission.Advantageously, the device comprises a ramp provided with at least one nozzle (preferably two nozzles), the distal end of which is fixed, via the support, on the transmission system.

De préférence, ledit support central comporte des moyens permettant de régler en hauteur la rampe.Preferably, said central support comprises means for adjusting the height of the ramp.

La figure 1 montre en vue de dessus les différents éléments que comporte le dispositif de l'invention, à l'exception du réservoir de liquide à épandre.The figure 1 shows in top view the various elements that comprises the device of the invention, with the exception of the liquid reservoir to be spread.

Le dispositif de l'invention comporte ainsi :

  • une série de tiges 1 à 6 (formant une perche), d'une longueur d'environ 1,5 m à 3 m chacune, de préférence constituée de fibres de carbone ou fibre de verre;
  • un chariot 7 disposé à l'extrémité d'une des tiges référencée 1 dite tige terminale ;
  • un tuyau flexible d'alimentation en liquide, référencé 8, et montré enroulé en rond sur la figure 1,
  • une rampe 10 de buses destinées à pulvériser le liquide, cette rampe 10 étant portée par le chariot 7.
The device of the invention thus comprises:
  • a series of rods 1 to 6 (forming a pole), of a length of about 1.5 m to 3 m each, preferably made of carbon fiber or fiberglass;
  • a carriage 7 disposed at the end of one of the rods referenced 1 as the terminal rod;
  • a liquid supply hose, referenced 8, and shown wound in a circle on the figure 1 ,
  • a ramp 10 of nozzles for spraying the liquid, this ramp 10 being carried by the carriage 7.

Le flexible 8 comporte :

  • une extrémité 8B destinée à être reliée à une motopompe (non représentée) elle-même reliée à une source d'alimentation en liquide tel qu'un réservoir (non représenté) ;
  • une extrémité 8A destinée à être reliée à la rampe 10 de buses.
The hose 8 comprises:
  • an end 8B intended to be connected to a motor pump (not shown) itself connected to a liquid supply source such as a reservoir (not shown);
  • an end 8A intended to be connected to the ramp 10 of nozzles.

En position montée du flexible 8, celui-ci court le long de la perche en étant avantageusement porté par chaque tige 1 à 6 et en y étant maintenu par des moyens de fixation connus, tels que des colliers ou des languettes repliées sur elles-mêmes (figure 3).In the mounted position of the hose 8, it runs along the pole being advantageously carried by each rod 1 to 6 and being held there by known fastening means, such as collars or tongues folded on themselves ( figure 3 ).

Le chariot 7, décrit ultérieurement en détail, comporte principalement :

  • un essieu 9 à chaque extrémité duquel est monté une roue ou un galet à rotation libre 11 A, respectivement 11 B ; et
  • la rampe 10 portant à chacune de ses extrémités une buse 12 et 13 de pulvérisation de liquide.
The carriage 7, described in detail later, mainly comprises:
  • an axle 9 at each end of which is mounted a wheel or a freely rotating roller 11A, respectively 11B; and
  • the ramp 10 carrying at each of its ends a nozzle 12 and 13 for spraying liquid.

Les roues sont démontables.The wheels are removable.

Chaque extrémité de chaque tige est pourvue de moyens de solidarisation d'une tige à la suivante, de manière que les tiges soient disposées les unes à la suite des autres, pour former une longue perche de 10 ou 15 m, voire plus. Les tiges présentent des sections croissantes, en partant de la tige d'extrémité distale 1, jusqu'à la tige proximale 6, dont l'extrémité proximale 6A est destinée à être tenue par la main ou les mains d'un utilisateur (non représentés), à l'opposé du chariot 7.Each end of each rod is provided with means for securing a rod to the next, so that the rods are arranged one after the other, to form a long pole of 10 or 15 m or more. The stems have increasing sections, from the distal end shaft 1, to the proximal shaft 6, the proximal end 6A is intended to be held by the hand or the hands of a user (not shown ), opposite the carriage 7.

La figure 2 montre une vue de détail en perspective, du chariot 7 et de la rampe 10. Cette dernière est fixée, par l'intermédiaire d'une équerre en L 14 comportant une patte verticale 14A et une patte horizontale 14 B (qui n'est pas visible sur la figure 2).The figure 2 shows a detailed perspective view of the carriage 7 and the ramp 10. The latter is fixed, via an L-shaped bracket 14 having a vertical leg 14A and a horizontal leg 14 B (which is not visible on the figure 2 ).

A l'extrémité de la patte verticale 14A est fixé un élément 16 de raccordement de fluide, raccordé d'une part à l'extrémité 8A du flexible 8, et d'autre part à la rampe 10 par un tube court 17 de raccordement.At the end of the vertical lug 14A is fixed a fluid connection element 16, connected on the one hand to the end 8A of the hose 8, and on the other hand to the ramp 10 by a short connecting tube 17.

La patte horizontale 14 B de l'équerre 14 est fixée d'une part à un système de transmission 15 qui à son tour est fixé sur l'essieu 9, et d'autre part à l'extrémité distale 1A de la tige terminale 1. Le système de transmission 15 est destiné à piloter mécaniquement l'orientation de l'essieu 9 en agissant sur l'extrémité 1 A de la tige terminale 1.The horizontal lug 14 B of the bracket 14 is fixed on the one hand to a transmission system 15 which in turn is fixed on the axle 9, and on the other hand to the distal end 1A of the end rod 1 The transmission system 15 is intended to mechanically drive the orientation of the axle 9 by acting on the end 1 A of the end rod 1.

La rampe 10 est constituée de deux tubes colinéaires 10A et 10B dont l'extrémité proximale respective est raccordée au tube de raccordement 17, et dont l'extrémité distale respective porte les buses 12 et 13.The ramp 10 consists of two collinear tubes 10A and 10B whose respective proximal end is connected to the connecting tube 17, and whose respective distal end carries the nozzles 12 and 13.

La figure 3 montre le dispositif de l'invention, en cours d'utilisation sur une partie de toiture T, où l'on voit la tige terminale 1, le flexible 8, le chariot 7, portant la rampe 10 munie des deux buses 12 et 13.The figure 3 shows the device of the invention, in use on a roof portion T, where we see the end rod 1, the flexible 8, the carriage 7, carrying the ramp 10 provided with two nozzles 12 and 13.

Les roues 11 A et 11 B roulent ainsi sur la toiture T, la tige terminale 1 étant disposée parallèlement à la toiture T, selon la ligne de pente. Sur la figure 3, est visible la seule tige 1, à laquelle est raccordé l'ensemble des autres tiges.The wheels 11 A and 11 B thus roll on the roof T, the end rod 1 being arranged parallel to the roof T, according to the slope line. On the figure 3 , is visible the only rod 1, to which is connected all the other rods.

On comprend que l'utilisateur, en déplaçant la tige terminale 1, par l'intermédiaire de l'ensemble du train de tiges constituant la perche, peut déplacer le chariot 7 sur la toiture T, et donc les buses 12 et 13 par un mouvement de translation de la perche parallèlement à elle-même.It is understood that the user, by moving the terminal rod 1, through the whole of the drill string constituting the pole, can move the carriage 7 on the roof T, and therefore the nozzles 12 and 13 by a movement translation of the pole parallel to itself.

Selon l'invention, le chariot comporte des moyens permettant d'orienter les roues et qui sont actionnables à distance par l'utilisateur resté au sol. Ces moyens sont décrits ultérieurement en détail.According to the invention, the carriage comprises means for orienting the wheels and which are operable remotely by the user remained on the ground. These means are described later in detail.

Il est fait maintenant référence à la figure 4, qui montre de manière schématique l'ensemble des moyens et éléments de l'invention, permettant de commander à distance la vaporisation ou la pulvérisation de liquide à la sortie des buses 12 et 13.Now reference is made to figure 4 , which shows schematically all the means and elements of the invention, for remotely controlling the vaporization or the spraying of liquid at the outlet of the nozzles 12 and 13.

Par commodité, l'échelle n'est pas respectée sur la figure 4. On retrouve la rampe 10 munie des buses 12 et 13, représentées symboliquement et à petite échelle.For convenience, the scale is not respected on the figure 4 . We find the ramp 10 provided with nozzles 12 and 13, represented symbolically and on a small scale.

Le dispositif de l'invention comporte :

  • une source 18 de liquide à pulvériser, tel qu'un réservoir ou un conteneur ; le liquide est par exemple un liquide destiné à traiter une toiture T ou une façade.
  • une motopompe électrique 19 (du type connu en soi) destinée à injecter le liquide dans le flexible 8 ;
  • une électrovanne 21 dont le port amont d'entrée 21 A est relié par un flexible 22 au pulvérisateur 20, et dont le port aval de sortie 21 B est relié à l'extrémité 8B du flexible 8, proche de l'extrémité distale 6A de la perche ici non représentée ;
  • un émetteur 23 apte à commander à distance l'ouverture et la fermeture de l'électrovanne 21 ;
  • un organe de télécommande 24 apte à commander le fonctionnement de l'émetteur 23.
The device of the invention comprises:
  • a source 18 of liquid to be sprayed, such as a tank or a container; the liquid is for example a liquid for treating a roof T or a facade.
  • an electric pump motor 19 (of the type known per se) for injecting the liquid into the hose 8;
  • a solenoid valve 21 whose input upstream port 21 A is connected by a hose 22 to the sprayer 20, and whose downstream outlet port 21 B is connected to the end 8B of the hose 8, close to the distal end 6A of the pole here not shown;
  • a transmitter 23 adapted to remotely control the opening and closing of the solenoid valve 21;
  • a remote control member 24 adapted to control the operation of the transmitter 23.

Une source d'alimentation 25 en courant alternatif 220-230 V est reliée à un transformateur 26 qui délivre un courant continu 24 V pour l'électrovanne 21, tandis que l'émetteur 23 est relié à une autre source 27 d'alimentation en courant alternatif 220-230 V.A 220-230 V AC power source 25 is connected to a transformer 26 which supplies a 24 VDC for the solenoid valve 21, while the emitter 23 is connected to another power supply source 27. alternative 220-230 V.

L'organe de télécommande 24 comporte par exemple deux boutons de commande 28 et 29 ainsi qu'un voyant 30. Il présente par exemple une longueur d'environ 6 cm, une largeur de 3 cm, et une épaisseur d'environ 1 cm.The remote control member 24 comprises for example two control buttons 28 and 29 and a light 30. It has for example a length of about 6 cm, a width of 3 cm, and a thickness of about 1 cm.

Ainsi que montré sur la figure 5, l'organe de télécommande 24 est susceptible d'être fixé sur un brassard ou une lanière 31, de manière à être porté par l'utilisateur autour de son poignet ou de son bras, par enroulement du brassard ou de la lanière, dont les extrémités sont pourvues de moyens de solidarisation amovible connus en eux-mêmes et non représentés.As shown on the figure 5 , the remote control member 24 can be fixed on a cuff or a strap 31, so as to be worn by the user around his wrist or his arm, by winding the cuff or the strap, whose ends are provided with removable fastening means known in themselves and not shown.

On comprend que l'utilisateur, par l'intermédiaire de l'organe de télécommande 24, peut déclencher ou arrêter la pulvérisation. Par exemple, le bouton 28 sert à déclencher le dispositif et le mettre en opération, tandis que le bouton 29 permet de déclencher (ou d'arrêter) la pulvérisation, en actionnant l'électrovanne 21.It is understood that the user, through the remote control member 24, can trigger or stop the spraying. For example, the button 28 is used to trigger the device and put it into operation, while the button 29 can trigger (or stop) the spray, by operating the solenoid valve 21.

En variante (non représentée), il est possible de raccorder la motopompe 19 à une seconde électrovanne, elle-même reliée à un second émetteur d'une part et à une seconde perche avec buses, le second ensemble étant actionnable par une seconde télécommande par un second utilisateur.Alternatively (not shown), it is possible to connect the pump 19 to a second solenoid valve, itself connected to a second emitter on the one hand and a second boom with nozzles, the second set being actuated by a second remote control by a second user.

En référence aux figures 6 à 10, on décrit ci-après les moyens permettant d'orienter à distance les roues du chariot 7.With reference to Figures 6 to 10 the means for remotely orienting the wheels of the carriage 7 are described below.

Les figures 6 à 10 sont des vues de détail du chariot, montrant :

  • l'essieu 9 constitué de deux parties respectives gauche 9A et droite 9B, colinéaires, et à chaque extrémité distale de laquelle est montée à rotation libre une roue (respectivement 11 A et 11 B) ;
  • le système de transmission 15 qui à son tour est fixé sur la partie centrale de l'essieu 9 ;
  • l'équerre 14 en L dont la branche horizontale 14 B est fixée sur la partie supérieure du système de transmission 15 ; sur la partie verticale 14A est fixé l'élément de raccordement 16 lui-même raccordé en amont à l'extrémité distale 8A du flexible d'alimentation 8 ;
  • dans la partie inférieure de la patte verticale 14A est fixée l'extrémité distale 1 A de la tige d'extrémité 1 (figure 7).
The Figures 6 to 10 are detailed views of the cart, showing:
  • the axle 9 consists of two respective left 9A and straight 9B collinear parts, and each distal end of which is mounted to free rotation a wheel (respectively 11A and 11B);
  • the transmission system 15 which in turn is fixed to the central portion of the axle 9;
  • the L-shaped bracket 14, the horizontal arm 14 B of which is fixed to the upper part of the transmission system 15; on the vertical portion 14A is fixed the connecting element 16 itself connected upstream to the distal end 8A of the supply hose 8;
  • in the lower part of the vertical leg 14A is fixed the distal end 1A of the end rod 1 ( figure 7 ).

L'essieu 9 peut être constitué de tiges télescopiques permettant de régler sa longueur et donc l'écartement des roues.The axle 9 may consist of telescopic rods to adjust its length and thus the spacing of the wheels.

La figure 9 montre une vue de dessous de l'ensemble du chariot montré sur les figures 6 à 10. Les figures 8 et 10 montrent le chariot respectivement en vue de face et en légère perspective, et en perspective de côté. Sur la figure 10, pour des raisons de clarté, le flexible 8 et la tige d'extrémité 1 A ont été omis.The figure 9 shows a bottom view of the entire cart shown on the Figures 6 to 10 . The figures 8 and 10 show the carriage respectively in front view and in slight perspective, and side perspective. On the figure 10 for reasons of clarity, the hose 8 and the end rod 1 A have been omitted.

Le système de transmission 15 est constitué d'un bloc cylindrique d'environ 5 à 7 cm de diamètre, et d'environ 2 cm d'épaisseur. Le système de transmission 15 comporte ainsi deux parties concentriques, l'une sur l'autre, à savoir une partie supérieure solidaire de l'équerre 14, et une partie inférieure solidaire de l'essieu 9 par l'intermédiaire d'une bride 15A. La partie inférieure du système de transmission 15 peut tourner par rapport à la partie supérieure, selon un axe vertical central commun.The transmission system 15 consists of a cylindrical block about 5 to 7 cm in diameter, and about 2 cm thick. The transmission system 15 thus comprises two concentric parts, one on the other, namely an upper part integral with the bracket 14, and a lower part secured to the axle 9 by means of a flange 15A. . The lower part of the transmission system 15 is rotatable relative to the upper part, along a common central vertical axis.

Le système de transmission comporte à l'intérieur des engrenages (qui ne sont pas visibles sur les figures), à savoir un premier pignon solidaire de l'extrémité de la tige d'extrémité 1A, et un second pignon solidaire de la partie supérieure du système de transmission 15, et donc de la bride 15A, et ainsi de l'essieu 9.The transmission system has inside gears (which are not visible in the figures), namely a first pinion integral with the end of the end rod 1A, and a second pinion integral with the upper part of the transmission system 15, and therefore of the flange 15A, and thus of the axle 9.

L'ensemble des tiges 1 à 6 qui constituent la perche, tenue à une extrémité proximale ou à l'extrémité distale 6A par l'utilisateur, et pourvue du chariot 7 à l'extrémité distale opposée, est susceptible d'être tournée sur elle-même, sur un axe longitudinal, comme montré sur la figure 11D, de manière schématique, par une relation selon un angle par exemple d'environ 20°à 60°The set of rods 1 to 6 which constitute the pole, held at a proximal end or at the distal end 6A by the user, and provided with the carriage 7 at the opposite distal end, may be turned on it same, on a longitudinal axis, as shown on the figure 11D , schematically, by a relationship at an angle for example of about 20 ° to 60 °

On décrit ci-après, en regard des figures 11A à 11C, en vue de dessus, les différentes orientations angulaires des roues 11 A et 11 B.We describe below, next to Figures 11A to 11C , in plan view, the different angular orientations of the wheels 11 A and 11 B.

Sur la figure 11A, les roues sont disposées de manière que l'essieu soit perpendiculaire à l'axe longitudinal de la tige d'extrémité 1A. Cet axe constitue l'axe de déplacement de la perche maniée par l'utilisateur, donc parallèlement à elle-même.On the figure 11A the wheels are arranged so that the axle is perpendicular to the longitudinal axis of the end rod 1A. This axis is the axis of movement of the pole handled by the user, so parallel to itself.

Dans cette position, la rampe 10 est parallèle à l'essieu 9, et les buses 12 et 13 sont orientés de manière à pulvériser du liquide dans la direction longitudinale de déplacement de la perche, et donc du chariot.In this position, the ramp 10 is parallel to the axle 9, and the nozzles 12 and 13 are oriented so as to spray liquid in the longitudinal direction of movement of the pole, and therefore of the carriage.

En référence à la figure 11D, lorsque l'utilisateur, dont la main est représentée par la référence 33, fait subir à l'extrémité proximale 6A de la tige proximale 6 une rotation selon son axe, suivant l'une des flèches "f" ou "g", ceci entraîne également ipso facto la rotation de la tige d'extrémité 1A, et donc du pignon dont il est solidaireWith reference to the figure 11D when the user, whose hand is represented by the reference 33, makes the proximal end 6A of the proximal rod 6 rotate about its axis, according to one of the arrows "f" or "g", this also ipso facto causes the rotation of the end rod 1A, and therefore the pinion which it is secured

Ceci ainsi entraîne la rotation, par l'intermédiaire du second pignon, de l'essieu 9 par rapport à l'axe central du système de transmission 15, qui lui-même est solidaire de l'ensemble unitaire : tige extrémité 1 / rampe 10 / équerre de support 14 / élément de raccordement 16 / flexible d'alimentation 8.This thus causes rotation, via the second pinion, of the axle 9 with respect to the central axis of the transmission system 15, which itself is integral with the unitary assembly: rod end 1 / ramp 10 support bracket 14 / connection element 16 / supply hose 8.

Dans la position montrée sur la figure 11B, l'utilisateur a tourné sur elle-même la perche, et donc la partie terminale 1 A de la tige terminale 1. Ceci a entraîné la rotation des engrenages, donc la rotation de l'essieu 9 par rapport à l'axe vertical central du système de transmission 15, et par conséquent une orientation différente des roues.In the position shown on the Figure 11B , the user has turned on itself the pole, and therefore the end portion 1 A of the terminal rod 1. This has resulted in the rotation of the gears, so the rotation of the axle 9 relative to the central vertical axis of the transmission system 15, and therefore a different orientation of the wheels.

Il est entendu que le degré de rotation de la tige proximale 6 par l'utilisateur conditionne l'importance de la rotation angulaire de l'essieu 9. En particulier, sur la figure 11B, on a représenté la position de déviation ou d'orientation maximale des roues par rapport à l'axe longitudinal de la tige 1, dans un sens de rotation.It is understood that the degree of rotation of the proximal rod 6 by the user determines the importance of the angular rotation of the axle 9. In particular, on the Figure 11B the position of deflection or maximum orientation of the wheels with respect to the longitudinal axis of the rod 1 is shown in a direction of rotation.

Sur la figure 11C, on a représenté le chariot 7 dans la position symétrique où les roues et l'essieu sont tournés dans l'autre direction selon la même amplitude.On the figure 11C , the carriage 7 is shown in the symmetrical position where the wheels and the axle are rotated in the other direction by the same amplitude.

Ainsi, en tournant la tige proximale 6 tenue par l'utilisateur, celui-ci peut orienter les roues dans l'un ou l'autre sens, selon une amplitude donnée, jusqu'à une valeur d'angle de rotation maximale montrée sur les figures 11B et 11C.Thus, by turning the proximal rod 6 held by the user, it can orient the wheels in one direction or the other direction, according to a given amplitude, up to a maximum rotation angle value shown on the Figures 11B and 11C .

Sur la figure 10, la patte verticale 14A présente plusieurs trous étagés verticalement, ce qui permet de régler la position en hauteur (par rapport à la surface de roulement des roues) de l'élément de raccordement 16, et donc de la rampe 10, et donc des buses 12 et 13.On the figure 10 the vertical lug 14A has several vertically stepped holes, which makes it possible to adjust the position in height (relative to the rolling surface of the wheels) of the connecting element 16, and therefore of the ramp 10, and therefore of the nozzles 12 and 13.

Sur les figures 12A et 12B, on a représenté le chariot vu de face en légère perspective de dessus, en deux positions différentes des buses, respectivement orientées angulairement vers le haut et vers le bas. Cette orientation est rendue possible par la rotation de la rampe 10 sur elle-même. Compte tenu de la position à environ 60°des buses par rapport à la rampe, ceci permet d'orienter la direction de pulvérisation du liquide des buses soit directement vers la surface à traiter, soit vers le haut de façon oblique.On the Figures 12A and 12B , the carriage is seen from the front in slight perspective from above, in two different positions of the nozzles respectively angularly oriented upwardly and downwardly. This orientation is made possible by the rotation of the ramp 10 on itself. Given the position at about 60 ° of the nozzles relative to the ramp, this allows to direct the direction of spraying the liquid of the nozzles either directly to the surface to be treated, or upwards obliquely.

Le fonctionnement du dispositif est le suivant, en référence notamment aux figures 4 et 5.The operation of the device is as follows, with particular reference to Figures 4 and 5 .

Dans un premier temps, l'utilisateur, disposant de l'ensemble du matériel, raccorde le réservoir 18 au flexible d'alimentation 8 à une extrémité, et à l'autre extrémité 8A, sur l'élément de raccordement 16 du chariot.At first, the user, having all the equipment, connects the reservoir 18 to the supply hose 8 at one end, and at the other end 8A, to the connection element 16 of the carriage.

Ensuite, l'utilisateur assemble les tiges les unes à la suite des autres, de manière à constituer la perche. Puis, l'extrémité 1A de la tige d'extrémité 1 est fixée sur le chariot 7.Then, the user assembles the rods one after the other, so as to constitute the pole. Then, the end 1A of the end rod 1 is fixed on the carriage 7.

Dans le cas où un grand nombre de tiges sont assemblés les unes aux constitue une perche de grande longueur, par exemple de plus de 10 m, l'utilisateur fixe des petits chariots intermédiaires (figure 1), référencés 7A et 7B, notamment sur la tige terminale 1, et sur l'une des tiges intermédiaires, par exemple la tige 3. Ces chariots intermédiaires comportent une bride cylindrique fixée par serrage sur la tige correspondante, et associée à des tourillons ou des petits arbres, sur lequel sont montés à rotation libre deux roues ou galets, à l'instar du chariot 7.In the case where a large number of rods are assembled together is a long pole, for example more than 10 m, the user sets small intermediate carriages ( figure 1 ), referenced 7A and 7B, in particular on the end rod 1, and on one of the intermediate rods, for example the rod 3. These intermediate carriages comprise a cylindrical flange fixed by clamping on the corresponding rod, and associated with trunnions or small shafts, on which are mounted free rotation two wheels or rollers, like the carriage 7.

Ensuite, l'utilisateur installe sur son bras ou au poignet l'organe de télécommande 24, par l'intermédiaire du bracelet 31, puis branche le transformateur 26 et l'émetteur 23 sur les alimentations électriques en courant alternatif.Then, the user installs on his arm or wrist the remote control member 24, through the bracelet 31, and then connects the transformer 26 and the transmitter 23 on the AC power supplies.

Puis, il place le chariot 7 sur la surface à traiter, par exemple une toiture, ou une façade, en manoeuvrant la perche par l'intermédiaire de l'extrémité proximale 6A de la tige proximale 6.Then, he places the carriage 7 on the surface to be treated, for example a roof, or a facade, by operating the pole via the proximal end 6A of the proximal rod 6.

Alors, l'utilisateur déclenche et met en route l'émetteur, par le bouton de commande 28 de l'organe de télécommande 24.Then, the user triggers and starts the transmitter, by the control button 28 of the remote control member 24.

Enfin, il déclenche la vaporisation, par l'intermédiaire du second bouton 29 qui par l'intermédiaire de l'émetteur 23, commande l'électrovanne 21. Celle-ci à son tour autorise le passage du liquide qui est alors vaporisé par les buses 12 et 13.Finally, it triggers the vaporization, via the second button 29 which through the transmitter 23, controls the solenoid valve 21. This in turn allows the passage of the liquid which is then vaporized by the nozzles 12 and 13.

Lors de la vaporisation du liquide sur la surface à traitée, l'utilisateur déplace le chariot, par l'intermédiaire de la perche, dans un premier temps par exemple en faisant monter descendre le chariot selon une ligne de pente de la toiture, puis arrivé au sommet ou à la base du toit, il fait tourner les roues par une rotation de la perche en son extrémité 6A, ce qui permet d'orienter à distance le chariot dans une autre direction tout en le dirigeant vers le haut vers le bas selon une autre ligne de pente, parallèle au plan du toit.During the vaporization of the liquid on the surface to be treated, the user moves the carriage, via the pole, initially for example by raising the truck down a slope line of the roof, then arrived at the top or at the base of the roof, it turns the wheels by a rotation of the pole at its end 6A, which makes it possible to remotely orient the carriage in another direction while directing it upwards according to another line of slope, parallel to the roof plan.

À tout moment, utilisateur peut arrêter la pulvérisation, tout en maintenant la perche d'une main, en appuyant sur le bouton d'arrêt 29 de l'organe de télécommande 24.At any time, the user can stop spraying, while holding the pole with one hand, by pressing the stop button 29 of the remote control member 24.

Le dispositif de l'invention représente une commodité et une sécurité d'utilisation optimale.The device of the invention represents an optimum convenience and safety of use.

Les éléments ou organes tels que l'émetteur 23 et l'électrovanne 21 peuvent être disposés dans un sac de portage à dos. Pour les petites quantités de liquide, il est encore envisageable de disposer dans un sac de portage à dos, également un réservoir de liquide à pulvériser.The elements or members such as the transmitter 23 and the solenoid valve 21 can be arranged in a backpack carrying bag. For small amounts of liquid, it is still conceivable to have in a backpacking bag, also a tank of liquid to be sprayed.

La présente invention n'est pas limitée aux modes de réalisation décrits et représentés, mais inclut toutes variantes.The present invention is not limited to the embodiments described and shown, but includes all variants.
