Cet outil est adapté notamment pour préparer les surfaces métalliques d'aéronef.The invention relates to a portable tool for treating surfaces of any type, in particular sanding or sanding, comprising a suction system. This tool is particularly suitable for preparing the metal surfaces of aircraft.

Que ce soit lors de la préparation d'une pièce ou d'une partie de la structure d'un avion, lorsqu'assemblé ou en réparation, il peut être nécessaire de lisser une surface rugueuse. Pour ce faire, des outils d'égrenage ou de ponçage à aspiration sont utilisés. L'égrenage est un ponçage léger permettant d'éliminer des défauts et marques d'usinage sur ladite pièce ou partie de la structure de l'avion tout en préservant un état de surface correct.Whether when preparing a part or part of an aircraft structure, when assembled or under repair, it may be necessary to smooth a rough surface. To do this, vacuum ginning or sanding tools are used. Sanding is light sanding to eliminate defects and machining marks on said part or part of the aircraft structure while preserving a correct surface condition.

Le brevet FR3001169 déposé par Airbus Operations SAS décrit un outil de ce type à dispositif d'assistance. Un des problèmes posé par ce type d'outil est l'encombrement limitant voire interdisant l' accès à des zones restreintes ou présentant des obstacles tels que des fixations.The patent FR3001169 filed by Airbus Operations SAS describes a tool of this type with an assistance device. One of the problems posed by this type of tool is the bulk limiting or even prohibiting access to restricted areas or presenting obstacles such as fixings.

Cependant, elle ne se limite pas à cette application et peut concerner toute pièce, partie, structure d'un aéronef voire même d'un autre véhicule tel que par exemple une automobile, un navire, un train ou autres, voire même de toute autre structure.The present invention is illustrated in the following by taking the example of a fuselage panel 2 of an aircraft. However, it is not limited to this application and can concern any part, part, structure of an aircraft or even another vehicle such as for example an automobile, a ship, a train or others, or even any other structure.

Comme représenté de manière schématique sur les figures 2 et 4, l'outil 4 de traitement de surface comprend trois parties assurant chacune au moins une fonction propre : une partie 6 dédiée au traitement de surface, à l'aspiration et au guidage des particules aspirées dite partie de traitement de surface, une partie 8 dédiée à la récupération et au filtrage des particules ainsi qu'au logement d'un dispositif 10 d'aspiration proprement dit, appelée ci-après partie 8 de filtrage, une partie 12 assurant la connexion entre les deux se présentant dans la forme illustrée sous la forme d'un conduit 14. Le conduit est creux et constitué de tout type de matériau souple pour permettre l'enfilage décrit plus loin, par exemple en plastique souple. La partie 6 de traitement de surface doit être maintenue en fonctionnement au plus proche de la surface à traiter comme représenté sur la figure 1. La partie 8 de filtrage comprend un contenant 16 portable pour loger l'ensemble des systèmes nécessaires à l'aspiration, la récupération et le filtrage des particules. Ces trois parties 6, 8 et 12 peuvent former chacune un élément individuel indépendant ou être associé au moins partiellement à une autre partie pour ne former qu'un seul bloc. Dans la forme de réalisation illustrée, chacune des parties est indépendante pour mieux en assurer la maintenance et la portabilité. Chacune des parties étant portables, l'outil 4 de traitement de surface dans son ensemble est portable par un seul opérateur comme montré par les figures 1 et 3.As shown schematically on the figure 2 And 4 , the surface treatment tool 4 comprises three parts each ensuring at least one specific function: a part 6 dedicated to surface treatment, suction and guiding of the vacuumed particles called surface treatment part, a part 8 dedicated for the recovery and filtering of particles as well as for housing a suction device 10 properly said, hereinafter called filtering part 8, a part 12 ensuring the connection between the two being in the form illustrated in the form of a conduit 14. The conduit is hollow and made of any type of flexible material to allow the threading described below, for example in flexible plastic. The surface treatment part 6 must be kept in operation as close as possible to the surface to be treated as shown in the figure 1 . The filtering part 8 comprises a portable container 16 to house all of the systems necessary for suction, recovery and filtering of particles. These three parts 6, 8 and 12 can each form an independent individual element or be associated at least partially with another part to form only a single block. In the illustrated embodiment, each of the parts is independent to better ensure maintenance and portability. Each of the parts being portable, the surface treatment tool 4 as a whole is portable by a single operator as shown by the figures 1 and 3 .

La partie 6 dédiée au traitement de surface comprend un embout 18 amovible présentant une surface 20 adaptée au traitement souhaité avec lequel des particules sont projetées dans l'air au voisinage de l'opérateur d'où la nécessité de les aspirer. Les traitements nécessitant l'aspiration de particules sont variés : ponçage, égrenage, brossage, usinage comme par exemple la réalisation de mini-rayures, ou tout autre type de traitement. Dans le cas d'un ponçage ou d'un égrenage, la surface 20 est une surface abrasive ; dans la suite on utilise le terme ponçage pour couvrir indifféremment l'opération de ponçage comme d'égrenage. Dans le cas d'un brossage, la surface 20 porte des fibres, fils, filaments ou équivalents plus ou moins souples, plus ou moins longs. Dans le cas d'un usinage dont le but est de réaliser des mini-rayures, la surface est munie de mini-lames ou équivalents. Il peut être également nécessaire d'utiliser un embout permettant d'augmenter la rugosité pour favoriser l'accroche d'un revêtement. En conclusion, l'embout est équipé des éléments nécessaires à la réalisation du traitement souhaité. Afin de se protéger des particules 24 produites représentées schématiquement sur la figure 4, l'outil 4 comporte un équipement de protection sous la forme d'un gant 22 (figures 1 et 3) portant ledit embout 18. L'embout 18 peut être d'un seul tenant, d'un seul bloc ou comporter plusieurs briques 26 comme le montre la figure 5. Selon une première forme possible, il peut par exemple comporter deux briques : une première brique fixée au gant et une deuxième brique de traitement de surface et par exemple une brique de ponçage portant la surface abrasive. Dans cette configuration, le conduit 14 est connecté à l'une ou l'autre des briques. Les deux briques sont fixées l'une à l'autre de manière amovible. Le terme amovible sera compris dans toute la description comme signifiant détachable sans détériorer les surfaces de liaison en contact. La fixation amovible/détachable peut par exemple être réalisée par clipsage, ruban à boucles et crochets de type Velcro (marque déposée) ou autres. Dans la forme illustrée, les briques 26 sont fixées les unes aux autres par pression légère et maintenues ensemble par emboitement à légère interférence. Selon une autre configuration possible illustrée à la figure 5, l'embout 18 comporte trois briques 28, 30 et 32, une première 28 fixée au gant, dite brique de fixation, une deuxième 30, appelée brique d'aspiration fixée de manière amovible à celle-ci et à une troisième brique 32 dite de traitement de surface fixée de manière amovible à la deuxième brique 30 d'aspiration. La deuxième brique 30 d'aspiration est connectée au conduit 14 et la troisième brique 32 de traitement de surface et par exemple de ponçage porte la surface 20 adaptée au traitement souhaité soit dans l'exemple donné une surface abrasive. La première et deuxième configuration sont identiques à la seule différence près que la brique d'aspiration et la brique de fixation ne font qu'une dans la première.Part 6 dedicated to surface treatment comprises a removable tip 18 having a surface 20 adapted to the desired treatment with which particles are projected into the air in the vicinity of the operator hence the need to suck them up. The treatments requiring particle suction are varied: sanding, sanding, brushing, machining such as making mini-scratches, or any other type of treatment. In the case of sanding or ginning, surface 20 is an abrasive surface; In the following we use the term sanding to cover both the sanding and ginning operations. In the case of brushing, the surface 20 carries more or less flexible, more or less long fibers, threads, filaments or equivalents. In the case of machining whose aim is to produce mini-scratches, the surface is provided with mini-blades or equivalent. It may also be necessary to use a tip to increase the roughness to improve the adhesion of a coating. In conclusion, the tip is equipped with the elements necessary to carry out the desired treatment. In order to protect yourself from the particles 24 produced, represented schematically on the Figure 4 , the tool 4 includes protective equipment in the form of a glove 22 ( figures 1 and 3 ) carrying said end piece 18. The end piece 18 can be in one piece, in a single block or comprise several bricks 26 as shown in Figure 5 . According to a first possible form, it can for example comprise two bricks: a first brick fixed to the glove and a second surface treatment brick and for example a sanding brick carrying the abrasive surface. In this configuration, conduit 14 is connected to one or other of the bricks. Both bricks are removably attached to each other. The term removable will be understood throughout the description to mean detachable without damaging the connecting surfaces in contact. The removable/detachable attachment can for example be achieved by clipping, Velcro type hook and loop tape (registered trademark) or others. In the form illustrated, the bricks 26 are fixed to each other by light pressure and held together by interlocking with slight interference. According to another possible configuration illustrated in Figure 5 , the tip 18 comprises three bricks 28, 30 and 32, a first 28 fixed to the glove, called the fixing brick, a second 30, called the suction brick fixed removably to this and to a third brick 32 called surface treatment removably attached to the second suction brick 30. The second suction brick 30 is connected to the conduit 14 and the third brick 32 for surface treatment and for example sanding carries the surface 20 adapted to the desired treatment, in the example given an abrasive surface. The first and second configuration are identical with the only difference that the suction brick and the fixing brick are one in the first.

Chaque brique 26 dispose de deux faces de liaison opposées l'une à l'autre. La brique 28 de fixation présente une face 34A de liaison avec le gant 22 et une face opposée de liaison 34B avec la brique 30 d'aspiration. La brique 30 d'aspiration présente une face 30A de liaison avec la brique 28 de fixation et une face 30B opposée de fixation avec la brique 32 de traitement de surface. La brique 32 de traitement de surface présente une face 32A de liaison avec la brique 30 d'aspiration et une face 32B correspondant à la surface 20 adaptée au traitement souhaité et dans l'exemple du ponçage la surface abrasive. La face 34B de liaison du bloc de fixation comprend des parties 36 saillantes ou saillies de forme correspondante à des cavités 38 prévues débouchant sur la face 30A de liaison du bloc 30 d'aspiration. Les saillies 36 et cavités 38 sont emboitables avec une légère interférence pour permettre leur fixation amovible l'une à l'autre. Dans la forme illustrée, les saillies 36 et cavités 38 sont de forme parallélépipédique de section carrée mais pourraient être de forme différente par exemple cylindrique de section circulaire. Le même principe est utilisé pour les faces 30B et 32A de liaison permettant la fixation amovible entre la brique 30 d'aspiration et la brique 32 de traitement de surface. Toute forme est possible du moment que les briques soient fixées l'une à l'autre de manière amovible. Dans les formes illustrées, les briques 26 sont de forme parallélépipédique à section globalement rectangulaire.Each brick 26 has two connecting faces opposite each other. The fixing brick 28 has a face 34A for connection with the glove 22 and an opposite face for connection 34B with the suction brick 30. The suction brick 30 has a face 30A for connection with the fixing brick 28 and an opposite face 30B for fixing with the surface treatment brick 32. The surface treatment brick 32 has a face 32A connecting with the suction brick 30 and a face 32B corresponding to the surface 20 adapted to the desired treatment and in the example of sanding the abrasive surface. The connecting face 34B of the fixing block comprises protruding parts 36 or projections of shape corresponding to cavities 38 provided opening onto the connecting face 30A of the suction block 30. The projections 36 and cavities 38 are interlocking with a slight interference to allow their removable attachment to each other. In the form illustrated, the projections 36 and cavities 38 are of parallelepiped shape with a square section but could be of a different shape, for example cylindrical with a circular section. The same principle is used for the connecting faces 30B and 32A allowing removable attachment between the suction brick 30 and the surface treatment brick 32. Any shape is possible as long as the bricks are removably attached to each other. In the shapes illustrated, the bricks 26 are of parallelepiped shape with a generally rectangular section.

La brique 32 de traitement de surface est équipée comme vu précédemment du nécessaire pour réaliser le traitement de surface souhaité. Dans l'exemple du ponçage, la brique 32 comporte un consommable 40 abrasif, visible sur les figures 1 et 3, dont l'une des faces constitue la face 32B à surface abrasive. Le consommable 40 est collé à l'autre partie de la brique 32 par tout type de moyen et par exemple par collage. La brique de ponçage peut aussi former un seul bloc constitué dudit consommable (ou de l'équipement nécessaire à l'opération souhaitée dans le cas d'un autre type de traitement de surface). Les panneaux 2 sur lesquels l'outil 4 opère peuvent avoir des formes complexes, des reliefs variés, être pourvus d'éléments en saillie tels que des fixations 41 (visibles sur la figure 1). Comme représenté sur les figures 6, 7 et 8, l'outil 4 comprend un ensemble de briques 32 de traitement de surface et dans l'exemple illustré de ponçage de formes différentes choisies suivant la forme de la surface à traiter. Du fait d'être fixée de manière amovible à une autre brique et dans la deuxième configuration illustrée, à la brique 30 d'aspiration, l'opérateur peut changer la forme de la brique 32 de ponçage suivant la surface à traiter. Les figures 6 à 8 représentent plusieurs exemples de forme. La figure 6 illustre une brique 32 de forme parallélépipédique de section rectangulaire présentant une surface 20 abrasive plane. La figure 7 montre une brique 32 dont la surface 20 abrasive est de forme arrondie. La figure 8 illustre une brique 32 dont la section présente une section trapézoïdale rectangle, la grande et la petite base étant dans une direction perpendiculaire à la face 32A de liaison : ainsi la surface 20 abrasive est plane et inclinée par rapport à la face 32A formant un angle aigu avec face 42 latérale concernée (du côté de la grande base du trapèze). La partie 43 pointue formée au niveau de cet angle aigu permet à la brique de ponçage d'atteindre des zones difficiles d'accès. L'outil peut également comporter plusieurs briques de traitement de surface différentes : il peut par exemple être muni d'une brique de réalisation de mini-rayures, une brique de ponçage et une brique de brossage.The surface treatment brick 32 is equipped as seen previously with what is necessary to carry out the desired surface treatment. In the example of sanding, the brick 32 includes an abrasive consumable 40, visible on the figures 1 and 3 , one of the faces of which constitutes the face 32B with an abrasive surface. The consumable 40 is glued to the other part of the brick 32 by any type of means and for example by gluing. The sanding brick can also form a single block made up of said consumable (or of the equipment necessary for the desired operation in the case of another type of surface treatment). The panels 2 on which the tool 4 operates can have complex shapes, varied reliefs, be provided with projecting elements such as fixings 41 (visible on the figure 1 ). As shown on the figures 6 , 7 and 8 , the tool 4 comprises a set of surface treatment bricks 32 and in the illustrated example sanding bricks of different shapes chosen according to the shape of the surface to be treated. Due to being removably attached to another brick and in the second configuration illustrated, to the suction brick 30, the operator can change the shape of the sanding brick 32 depending on the surface to be treated. THE figures 6 to 8 represent several shape examples. There Figure 6 illustrates a brick 32 of parallelepiped shape of rectangular section having a flat abrasive surface 20. There Figure 7 shows a brick 32 whose abrasive surface 20 is rounded in shape. There figure 8 illustrates a brick 32 whose section has a rectangular trapezoidal section, the large and small base being in a direction perpendicular to the connecting face 32A: thus the abrasive surface 20 is flat and inclined relative to the face 32A forming an acute angle with lateral face 42 concerned (on the side of the large base of the trapezoid). The pointed part 43 formed at this acute angle allows the sanding brick to reach areas that are difficult to access. The tool can also include several different surface treatment bricks: it can for example be equipped with a brick for producing mini-scratches, a sanding brick and a brushing brick.

La brique 30 d'aspiration et la brique 32 de traitement de surface comprennent au moins un canal 44 intérieur et dans la forme illustrée et plus particulièrement visible sur la figure 4, un réseau de canaux 44 intérieurs longitudinal 46 et transversaux 48 permettant de guider l'air aspiré depuis la face 32B adaptée au traitement souhaité et par exemple abrasive jusqu'au conduit 14 extérieur de liaison avec la partie 8 d'évacuation et filtrage des particules 24. La face 32B adaptée au traitement souhaité comprend au moins une ouverture 50 d'aspiration par laquelle ou lesquelles un ou des canaux 48 transversaux aspirent l'air. Les canaux 48 transversaux de la brique de traitement de surface traversent la brique 32 de traitement de surface et viennent en correspondance avec des canaux 48 transversaux de la brique 30 d'aspiration. Lorsque les briques d'aspiration 30 et de traitement de surface 32 sont fixées l'une à l'autre, chaque canal 48 de l'une et de l'autre des briques est positionné de manière à ce qu'ils se joignent et ne forment plus qu'un seul et même canal transversal. L'une des faces 52 latérales de la brique d'aspiration comporte une ouverture 54 latérale en directe communication avec le conduit 14 extérieur. Dans la forme illustrée plus précisément, depuis cette ouverture 54, une portion 56 de conduit s'étend vers l'extérieur autour de laquelle s'enfile le conduit 14 extérieur. Un canal 46 longitudinal intérieur traverse longitudinalement une partie de la brique 30 d'aspiration pour déboucher dans ladite ouverture 54 latérale. L'une des extrémités des canaux 48 transversaux alignés des briques de traitement de surface et d'aspiration correspond aux ouvertures 50 d'aspiration et l'autre extrémité communique avec le canal 46 longitudinal. Ainsi les ouvertures 50 d'aspiration communiquent avec le conduit 14 extérieur à travers le réseau de canaux transversaux 48 et longitudinal 46 des briques de traitement de surface et d'aspiration.The suction brick 30 and the surface treatment brick 32 comprise at least one interior channel 44 and in the form illustrated and more particularly visible on the Figure 4 , a network of interior longitudinal 46 and transverse 48 channels 44 making it possible to guide the air sucked in from the face 32B adapted to the desired treatment and for example abrasive to the exterior conduit 14 connecting with the particle evacuation and filtering part 8 24. The face 32B adapted to the desired treatment comprises at least one suction opening 50 through which one or more 48 transverse channels suck in air. The transverse channels 48 of the surface treatment brick pass through the surface treatment brick 32 and correspond with transverse channels 48 of the suction brick 30. When the suction bricks 30 and surface treatment bricks 32 are attached to each other, each channel 48 of both bricks is positioned so that they join and do not form more than one and the same transverse channel. One of the side faces 52 of the suction brick has a side opening 54 in direct communication with the exterior conduit 14. In the form illustrated more precisely, from this opening 54, a portion 56 of conduit extends outwards around which the outer conduit 14 threads. An interior longitudinal channel 46 passes longitudinally through a part of the suction brick 30 to open into said lateral opening 54. One of the ends of the aligned transverse channels 48 of the surface treatment and suction bricks corresponds to the suction openings 50 and the other end communicates with the longitudinal channel 46. Thus the suction openings 50 communicate with the exterior conduit 14 through the network of transverse 48 and longitudinal 46 channels of the surface treatment and suction bricks.

La brique 28 de fixation est liée de manière amovible ou non avec le gant 22. Dans le cas d'une fixation amovible, le principe utilisé peut être identique à celui utilisé pour la fixation avec la brique d'aspiration à savoir par emboitement à interférence avec une brique faisant partie du gant ou par tout autre type de moyen connu. L'embout est positionné au niveau de l'extrémité d'un doigt 58 du gant 22 (figures 1 et 3). Le gant 22 est pris dans sa signification la plus générique à savoir toute pièce d'étoffe, cuir ou autre matériau susceptible d'envelopper une partie de la main pouvant être réduite à son strict minimum nécessaire à l'utilisation de l'outil. Dans la forme illustrée sur les figures, le gant 22 comprend une enveloppe 60 d'uniquement un doigt 58 de la main et plus particulièrement ici l'index et une extension 62 destinée à venir s'appliquer sur la face dorsale de la main portant deux brides de fixation au poignet dont une seule 64 est visible sur la figure 3. Les deux brides entourent le poignet et s'accrochent l'une à l'autre par tout type de moyen amovible. Elles peuvent selon une forme de réalisation comporter à l'une de leurs extrémités des textures différentes par exemple à boucles pour l'une et à crochets pour l'autre de type velcro (Marque déposée). Le gant peut être porté par la main droite comme la main gauche.The fixing brick 28 is linked in a removable manner or not with the glove 22. In the case of a removable fixing, the principle used can be identical to that used for fixing with the suction brick, namely by interference interlocking. with a brick forming part of the glove or by any other type of known means. The tip is positioned at the end of a finger 58 of the glove 22 ( figures 1 and 3 ). The glove 22 is taken in its most generic meaning, namely any piece of fabric, leather or other material capable of enveloping a part of the hand which can be reduced to the strict minimum necessary for the use of the tool. In the form illustrated in the figures, the glove 22 comprises an envelope 60 of only one finger 58 of the hand and more particularly here the index finger and an extension 62 intended to be applied to the dorsal face of the hand carrying two wrist fixing straps of which only one 64 is visible on the Figure 3 . The two straps surround the wrist and attach to each other by any type of removable means. According to one embodiment, they can have different textures at one of their ends, for example loops for one and hooks for the other, of the Velcro type (Registered trademark). The glove can be worn by either the right or left hand.

Les particules 24 émises telles que poussières, fibres ou autres contaminent l'air ambiant, les pièces avion et l'environnement de travail. La pollution engendrée sur les pièces avion peut être dommageable pour des opérations ultérieures telles que par exemple la peinture des pièces. Tout en usinant, il faut donc retirer les particules du milieu environnant le plus rapidement possible. L'utilisation de certaines particules comme les chromates peut être encadrée par des règlementations et il est recommandé d'éviter de les inhaler. L'outil 4 et plus particulièrement la partie 8 permet de les aspirer, les évacuer vers un filtre 67 qui les capte et les stocke dans le contenant 16.Particles 24 emitted such as dust, fibers or others contaminate the air ambient, aircraft parts and the working environment. The pollution generated on aircraft parts can be harmful for subsequent operations such as, for example, the painting of the parts. While machining, particles must therefore be removed from the surrounding environment as quickly as possible. The use of certain particles such as chromates may be subject to regulations and it is recommended to avoid inhaling them. Tool 4 and more particularly part 8 allows them to be sucked up and evacuated to a filter 67 which captures them and stores them in container 16.

Le contenant 16 qui peut présenter tout type de forme revêt dans la forme illustrée une forme globale cylindrique de section circulaire. Dans le contenant 16, est logé le dispositif d'aspiration 10. Le dispositif 10 ne sera pas décrit en détail : il se présente sous tout type de forme connue et par exemple celle d'aspirateurs portables classiques. Le contenant 16 présente un orifice 68 d'aspiration par lequel les particules 24 sont aspirées par le dispositif 10. Dans la forme illustrée plus précisément, depuis cette ouverture 68, une portion 70 de conduit s'étend vers l'extérieur autour de laquelle s'enfile le conduit 14 extérieur. A l'intérieur du contenant 16 au niveau de l'orifice 68, est prévue une valve 72 anti-retour. La valve 72 permet d'éviter le retour vers l'embout 18 et donc vers l'extérieur de particules 24 aspirées et particulièrement les particules évoquées plus haut qu'il est préférable de ne pas inhaler. Il est également prévu à cet effet une capsule 74 de filtrage démontable muni du filtre 67 permettant d'intercepter certaines particules et dans l'exemple susmentionné notamment les particules chromate. Pour ce faire, le contenant 16 est susceptible d'être démonté ou peut présenter un capot permettant d'accéder à l'intérieur de celui-ci ou tout système permettant d'accéder à l'intérieur du contenant et de pouvoir démonter la capsule et/ou permettre la maintenance du dispositif 10 d'aspiration ou de toute autre pièce. La capsule présente un rebord 76 s'introduisant dans une fente 78 prévue dans le contenant 16. La capsule 74 est positionnée entre l'orifice 68 et le dispositif 10. De manière classique, une ouverture 80 d'évacuation est prévue du côté opposé à l'orifice 68 d'aspiration, derrière le dispositif 10 d'aspiration.The container 16, which can have any type of shape, has in the form illustrated an overall cylindrical shape of circular section. In the container 16, the suction device 10 is housed. The device 10 will not be described in detail: it is presented in any type of known form and for example that of conventional portable vacuum cleaners. The container 16 has a suction orifice 68 through which the particles 24 are sucked in by the device 10. In the form illustrated more precisely, from this opening 68, a portion 70 of conduit extends outwards around which s thread the outer conduit 14. Inside the container 16 at the orifice 68, a non-return valve 72 is provided. The valve 72 makes it possible to avoid the return towards the nozzle 18 and therefore towards the outside of aspirated particles 24 and particularly the particles mentioned above which it is preferable not to inhale. For this purpose there is also provided a removable filtering capsule 74 provided with filter 67 making it possible to intercept certain particles and in the aforementioned example in particular chromate particles. To do this, the container 16 can be dismantled or can have a cover allowing access to the interior thereof or any system allowing access to the interior of the container and being able to dismantle the capsule and /or allow maintenance of the suction device 10 or any other part. The capsule has a rim 76 entering into a slot 78 provided in the container 16. The capsule 74 is positioned between the orifice 68 and the device 10. Conventionally, an evacuation opening 80 is provided on the side opposite to the suction orifice 68, behind the suction device 10.

Le contenant 16 peut être porté d'une quelconque manière par un unique opérateur ; deux alternatives sont illustrées. Sur la figure 9, le contenant 16 est porté en bandoulière 80 et sur la figure 10 au moyen d'un brassard 82 porté au bras. Que ce soit dans l'une ou l'autre des alternatives, dans les formes illustrées, le contenant 16 comprend un moyen 84 de fixation amovible à un support 86 porté par la bandoulière 80 ou le brassard 82 de type connu. Le support 86 présente sur sa surface extérieure des moyens permettant d'attacher de manière amovible les briques 32 de traitement de surface non utilisées, et par exemple à l'aide de surfaces à boucles et crochets de type Velcro (Marque déposée) prévue sur chaque brique de traitement de surface et sur le support. Sur la figure 9, la bandoulière 80 est attachée aux extrémités latérales du support 86 par deux crochets, mousquetons ou équivalent 88, 90. Sur la figure 10, le brassard 82 comprend une armature ici en plastique incorporant le support 86. Le moyen 84 de fixation du contenant comprend par exemple ici un support 92 à ergots du côté du support 86 et une cavité 94 à fentes du côté du contenant qui en se superposant permettent l'insertion du support 92 dans la cavité 94 de forme correspondante et son verrouillage en position en faisant pivoter le contenant par rapport au support.The container 16 can be carried in any way by a single operator; two alternatives are illustrated. On the Figure 9 , the container 16 is carried over the shoulder 80 and on the Figure 10 by means of an cuff 82 worn on the arm. Whether in one or other of the alternatives, in the forms illustrated, the container 16 comprises a means 84 for removable attachment to a support 86 carried by the shoulder strap 80 or the armband 82 of known type. The support 86 has on its exterior surface means making it possible to removably attach the unused surface treatment bricks 32, and for example using Velcro type hook and loop surfaces (Registered trademark) provided on each surface treatment brick and on the support. On the Figure 9 , the shoulder strap 80 is attached to the lateral ends of the support 86 by two hooks, carabiners or equivalent 88, 90. On the Figure 10 , the cuff 82 comprises a frame here made of plastic incorporating the support 86. The means 84 for fixing the container comprises for example here a support 92 with lugs on the side of the support 86 and a cavity 94 with slots on the side of the container which by superimposing allow the insertion of the support 92 into the cavity 94 of corresponding shape and its locking in position by rotating the container relative to the support.

Lorsqu'un opérateur souhaite traiter une surface, il suit les étapes suivante : - il commence par choisir une brique 32 de traitement de surface suivant la forme de la surface à traiter ; - il met la brique de traitement de surface en place sur la ou les briques déjà fixées au gant ; - il place le gant sur sa main, en particulier ici sur son index ; -il fixe ensuite le contenant sur une partie de son corps, comme vu précédemment par exemple sur le bras à l'aide d'un brassard ou en bandoulière. Ces étapes peuvent être réalisées dans un ordre différent. L'opérateur actionne le dispositif d'aspiration (par tout type de moyen connu tel qu'un bouton accessible depuis l'extérieur du contenant) et peut traiter la surface du panneau 2 concerné à l'aide de la brique de traitement de surface portée au doigt. Comme représenté par les flèches sur la figure 4, les particules 24 sont aspirées par le dispositif 10 d'aspiration. Elles sont guidées depuis l'ouverture 50 d'aspiration au travers des canaux 48 transversaux, longitudinal 46, du conduit 14 dans le contenant 16 duquel elles ne peuvent plus s'échapper grâce à la valve anti-retour 72. Elles sont alors captées par le filtre 67 de la capsule 74. Une fois le traitement de surface terminé, l'opérateur peut ouvrir le contenant 16 pour accéder à la capsule et la démonter afin de nettoyer le filtre.When an operator wishes to treat a surface, he follows the following steps: - he begins by choosing a surface treatment brick 32 following the shape of the surface to be treated; - he places the surface treatment brick in place on the brick(s) already attached to the glove; - he places the glove on his hand, in particular here on his index finger; -he then fixes the container on a part of his body, as seen previously for example on the arm using an armband or over the shoulder. These steps can be performed in a different order. The operator activates the suction device (by any type of known means such as a button accessible from outside the container) and can treat the surface of the panel 2 concerned using the surface treatment brick carried on your finger. As shown by the arrows on the Figure 4 , the particles 24 are sucked up by the suction device 10. They are guided from the suction opening 50 through the transverse channels 48, longitudinal 46, of the conduit 14 into the container 16 from which they can no longer escape thanks to the non-return valve 72. They are then captured by the filter 67 of the capsule 74. Once the surface treatment is completed, the operator can open the container 16 to access the capsule and dismantle it in order to clean the filter.

La présente invention propose donc un dispositif simple et maniable de traitement de surface à aspiration de particules produites par l'opération permettant de protéger l'opérateur, de suivre les contours de la surface à poncer, d'aller au plus près des éléments faisant obstacle, et de filtrer les particules et plus particulièrement les particules polluantes comme celles de chromate.The present invention therefore proposes a simple and handy surface treatment device with suction of particles produced by the operation making it possible to protect the operator, to follow the contours of the surface to be sanded, to get as close as possible to the elements obstructing , and to filter particles and more particularly polluting particles such as chromate.
