Description

La présente invention concerne un aspirateur à poussières, et plus particulièrement une amélioration de l'ergonomie du suceur d'aspirateur constituant l'organe de collecte des déchets souillant la surface à nettoyer.The present invention relates to a dust vacuum cleaner, and more particularly an improvement of the ergonomics of the vacuum cleaner constituting the waste collection member that contaminates the surface to be cleaned.

Il est connu, dans le domaine des suceurs d'aspirateur, une connexion par une articulation entre le suceur et le tube de liaison relié au corps d'aspirateur. Cette liaison procure de la souplesse et facilite le passage par le va-et-vient du suceur lors de l'opération de nettoyage.It is known, in the field of vacuum sucking, a connection by an articulation between the nozzle and the connecting tube connected to the body vacuum. This connection provides flexibility and facilitates the passage through the back and forth of the nozzle during the cleaning operation.

Le document FR 2 439 577 présente une amélioration de ce dispositif par un suceur d'aspirateur comportant une double articulation entre la base du suceur où sont localisés les canaux d'aspiration et le tube de liaison reliant le suceur à l'aspirateur.Document FR 2 439 577 shows an improvement of this device by a suction nozzle having a double articulation between the base of the where the suction channels and the connecting tube connecting the vacuum cleaner.

Un tel suceur permet une utilisation facilitée : indépendamment des sols nettoyés, notamment par la présence d'une des articulations en dehors de la surface active d'aspiration, qui permet de réduire la force de poussée du suceur lors du nettoyage. En effet, notamment lorsque le suceur est déplacé vers l'avant, la composante verticale de la force de poussée du suceur est directement exercée sur les roues et non sur la semelle ce qui permet de supprimer l'augmentation du frottement du suceur sur le sol.Such a nozzle makes it easier to use: independently of the floors cleaned, especially by the presence of one of the joints outside the active suction surface, which reduces the thrust force of the nozzle during cleaning. Indeed, especially when the nozzle is moved forward, the vertical component of the thrust force of the nozzle is directly exerted on the wheels and not on the sole which makes it possible to to suppress the increase of the friction of the nozzle on the ground.

Toutefois, la déportation d'une des articulations en dehors de la surface active d'aspiration allonge considérablement la forme du suceur, ce qui nuit à sa maniabilité. De plus, la roue, liée à cette articulation excentrée, rend la manoeuvre du suceur assez délicate et inconfortable.However, the deportation of one of the joints outside the surface active suction considerably lengthens the shape of the nozzle, which its maneuverability. In addition, the wheel, linked to this eccentric articulation, makes the Maneuver the sucker quite delicate and uncomfortable.

La présente invention vise à pallier les inconvénients de l'art antérieur en présentant un suceur aux performances améliorées pour une pluralité de sols, tout en gardant une forme compacte au suceur.The present invention aims to overcome the disadvantages of the prior art by having an improved performance nozzle for a plurality of soils, while keeping a compact shape to the nozzle.

Selon l'invention, le suceur d'aspirateur est ouvert vers la surface à nettoyer par au moins un canal d'aspiration ménagé dans la semelle du suceur et relié, par deux tubulures articulées, à un tube de liaison connecté à un bâti d'aspirateur, la première tubulure étant articulée sur la semelle, la seconde tubulure étant articulée sur la première, à distance de celle-ci, selon des axes sensiblement parallèles, ledit suceur comportant au moins une roue susceptible d'être proéminente par rapport à la semelle, ladite roue étant montée sur l'axe d'articulation de la seconde tubulure, le suceur comportant par ailleurs un capot recouvrant la semelle, caractérisé en ce que les points d'articulation de la seconde tubulure sur la première sont situés entre la semelle et le capot, et en ce que la semelle comporte des ouvertures de passage des roues.According to the invention, the suction nozzle is open towards the surface at cleaning by at least one suction channel formed in the sole of the nozzle and connected, by two articulated pipes, to a connecting tube connected to a frame of vacuum cleaner, the first tube being articulated on the sole, the second tubing being articulated on the first, at a distance from the latter, along axes substantially parallel, said nozzle having at least one wheel to be prominent relative to the sole, said wheel being mounted on the axis articulation of the second manifold, the nozzle further comprising a hood covering the sole, characterized in that the points of articulation of the second tubing on the first are located between the sole and the hood, and that the sole has openings for passage of the wheels.

La matérialisation des deux tubulures articulées à l'intérieur du suceur permet à ce dernier de garder une allure compacte, également par les ouvertures de passage des roues ménagées dans la semelle. De plus un tel agencement ne nuit pas à la maniabilité du suceur, puisque les roues sont à proximité des canaux d'aspiration. Au contraire, en disposant les deux articulations au coeur même du suceur, les mouvements donnés aux articulations sont répercutés rapidement au suceur, par l'effet de levier.The materialization of the two articulated pipes inside the nozzle allows the latter to keep a compact pace, also by passage openings for the wheels in the sole. In addition, such arrangement does not interfere with the handling of the nozzle, since the wheels are near the suction channels. On the contrary, by arranging both joints at the very heart of the sucker, the movements given to the joints are passed quickly to the squeegee, through leverage.

L'un des avantages de cette disposition réside dans la sortie « automatique » des roues lorsque le suceur est tiré vers l'arrière. En effet, au cours d'expérience de maniement des suceurs d'aspirateur, il s'est avéré qu'un déplacement du suceur vers l'arrière génère un léger décollement du suceur, lorsque l'utilisateur tire sur le tube de liaison. L'efficacité du suceur s'en trouve alors diminuée.One of the advantages of this arrangement is the exit "Automatic" wheels when the nozzle is pulled back. Indeed, experience in handling vacuum suckers, it turned out that displacement of the nozzle towards the rear generates a slight detachment of the nozzle, when the user pulls on the connecting tube. The effectiveness of the nozzle is found then diminished.

Il paraít ainsi intéressant de procurer, sur de tels sols, une aide à l'utilisateur lorsqu'il déplace le suceur vers l'arrière afin d'éviter ce décollement du suceur. Or il s'avère que, par l'agencement proposé, naturellement, par la résultante des forces s'exerçant sur le suceur, lorsque l'utilisateur tire le suceur à lui, il tend à faire sortir les roues au travers de la semelle. Cet effet est ainsi particulièrement recherché afin de procurer une aide au déplacement lorsque le suceur est déplacé vers l'arrière. La force de déplacement du suceur par l'utilisateur est ainsi différente selon le sens de déplacement en favorisant le roulement du suceur sur le sol lorsqu'il est tiré vers l'arrière. It is therefore interesting to provide, on such soils, the user when he moves the nozzle to the rear to avoid this detachment of the nozzle. It turns out that, by the arrangement proposed, naturally, by the resultant forces exerted on the nozzle, when the user pulls the nozzle he tends to push the wheels out through the sole. This effect is particularly sought after to provide travel assistance when the Squeegee is moved backwards. The force of displacement of the nozzle by the user is thus different according to the direction of movement by favoring the Sucker bearing on the ground when pulled back.

Avantageusement, la première tubulure est reliée, à l'opposé de la seconde tubulure, à une zone de raccordement débouchant sur le ou les canaux d'aspiration.Advantageously, the first tubing is connected, in opposition to the second manifold, to a connection zone leading to the suction channels.

La présence d'une pièce supplémentaire entre les tubulures articulées et les canaux d'aspiration permet à ces tubulures, et notamment à la première tubulure, d'être très courte.The presence of an additional piece between the articulated pipes and the suction channels allows these tubings, and in particular to the first tubing, to be very short.

Cette tubulure est d'autant plus courte que la zone de raccordement est rapportée sur la semelle et s'étend longitudinalement vers l'arrière de ladite semelle. Des valeurs inférieures à 5 cm sont ainsi atteintes en ce qui concerne la longueur de la première tubulure articulée.This tubing is even shorter than the connection zone is reported on the sole and extends longitudinally rearward of said sole. Values less than 5 cm are thus reached with regard to the length of the first articulated pipe.

De façon analogue, afin que la conduite du suceur reste efficace et agréable, la distance entre les axes de rotation des tubulures est de préférence inférieure à 5 cm, ce qui permet, simplement par une faible rotation de la seconde tubulure, de sortir ou non les roues de la semelle.In a similar way, so that the driving of the nozzle remains effective and pleasant, the distance between the axes of rotation of the tubes is preferably less than 5 cm, which allows, simply by a slight rotation of the second tubing, to leave or not the wheels of the sole.

Avantageusement, le suceur d'aspirateur est de forme sensiblement triangulaire en présentant notamment deux bords latéraux formant la pointe du suceur, ledit suceur comportant deux canaux agencés le long des deux bords latéraux formant la pointe du suceur, et en ce que les ouvertures de passage de roues sont localisées sensiblement autour du centre de gravité de la base triangulaire de la semelle.Advantageously, the vacuum nozzle is substantially shaped triangular shape, in particular with two lateral edges forming the tip of the nozzle, said nozzle having two channels arranged along both edges sides forming the tip of the nozzle, and in that the openings of passage wheels are located around the center of gravity of the base triangular of the sole.

Une telle architecture, notamment en disposant les roues au voisinage du centre de gravité de la semelle triangulaire et non en périphérie comme c'est généralement le cas dans les suceurs rectangulaires, permet d'équilibrer l'ensemble lorsque les roues sont actives.Such an architecture, in particular by arranging the wheels in the vicinity of the center of gravity of the triangular sole and not the periphery as it is usually the case in rectangular suckers, helps to balance all when the wheels are active.

Par ailleurs, lorsque l'utilisateur fait tourner le suceur par l'inclinaison du coude situé au niveau de la crosse de manipulation du suceur, ce dernier peut tourner sur lui-même, favorisant ainsi sa maniabilité lors de contournement d'obstacles.Moreover, when the user rotates the nozzle by the inclination of the elbow located at the handle of the squeegee, the latter can turn on itself, favoring its handling during bypass obstacles.

La présente invention concerne un suceur 1 d'aspirateur. Un tel suceur possède des conduits 31, 30 ainsi qu'un tube 2 de liaison à un corps d'aspirateur, non représenté, possédant notamment un moto-ventilateur susceptible de créer un flux d'aspiration d'air.The present invention relates to a vacuum nozzle 1. Such a nozzle has conduits 31, 30 and a tube 2 for binding to a body vacuum cleaner, not shown, including a motorcycle fan likely to create an air intake flow.

Le conduit 31 débouche au niveau de la semelle 11 du suceur en contact avec le sol à nettoyer, par l'intermédiaire d'une pièce 33 délimitant en partie une zone de raccordement 32 débouchant sur les canaux d'aspiration. Ces canaux sont généralement configurés selon la forme du suceur, afin d'optimiser l'efficacité d'aspiration. Dans l'exemple présenté où le suceur est de forme triangulaire, les canaux d'aspiration s'étendent en partie le long des deux bords 5, 6 formant la pointe du suceur, ainsi que dans ladite pointe du suceur après s'être rejoints dans la partie centrale 21 du suceur.The conduit 31 opens at the sole 11 of the nozzle in contact with the soil to be cleaned, via a part 33 defining in part a connection area 32 opening on the suction channels. These channels are usually configured according to the shape of the nozzle, so to optimize the suction efficiency. In the example presented where the nozzle is triangular shape, the suction channels extend partly along the two edges 5, 6 forming the tip of the nozzle, as well as in said tip of the nozzle after joining in the central portion 21 of the nozzle.

Avantageusement, la zone angulaire formant la pointe du suceur comporte un orifice frontal 7 destiné à assurer une aspiration dans une direction sensiblement parallèle à la surface à nettoyer.Advantageously, the angular zone forming the tip of the nozzle comprises a front orifice 7 intended to ensure suction in a direction substantially parallel to the surface to be cleaned.

Par ailleurs, dans la forme de réalisation présentée, le suceur possède des brosses escamotables actionnées par une pédale 8 pivotante. Cette pédale 8 est accessible au niveau du capot 12 du suceur. Ce dernier, dans cet exemple de réalisation, ne présente essentiellement que des fonctions esthétiques et de protection de l'environnement.Moreover, in the embodiment shown, the nozzle has retractable brushes actuated by a pedal 8 pivoting. This pedal 8 is accessible at the hood 12 of the nozzle. The latter, in this embodiment, essentially only presents functions aesthetic and environmental protection.

En effet, les canaux d'aspiration sont fermés, d'une part par une structure interne réalisée en partie lors de la fabrication par moulage de la semelle, telles les parties des canaux d'aspiration s'étendant le long des bords et débouchant par l'ouverture 7, mais également par la pièce supérieure 33 comportant en partie la zone de raccordement 32.Indeed, the suction channels are closed, on the one hand by a internal structure made in part during the manufacture by molding of the sole, such as the parts of the suction channels extending along the edges and opening through the opening 7, but also by the upper part 33 partly comprising the connection zone 32.

En effet, cette zone de raccordement 32 est obtenue par l'assemblage de la pièce supérieure 33 sur la semelle, à l'aide de trois vis disposées aux emplacements 16. D'autres moyens équivalents, tels des clips, peuvent être utilisés pour rapporter la pièce 33 sur la semelle. On peut également envisager une technique de bouterollage où des tétons en plastique issus de la semelle et sur lesquels sont rapportés la fenêtre sont fondus sur ladite fenêtre.Indeed, this connection zone 32 is obtained by the assembly of the upper piece 33 on the sole, using three screws arranged at the 16. Other equivalent means, such as clips, may be used to return the piece 33 on the sole. We can also consider a stubbing technique where plastic nipples from the sole and on which the window is reported are melted on said window.

Cette pièce supérieure 33, selon l'exemple de réalisation, comporte une zone de visualisation 14 des déchets sur la surface en cours de nettoyage, réalisée en rendant transparente une partie importante de ladite pièce triangulaire rapportée sur la semelle.This upper piece 33, according to the exemplary embodiment, comprises a viewing area 14 of the waste on the surface being cleaned, made by making transparent a significant part of said piece triangular reported on the sole.

Le capot 12 présente alors une simple ouverture en regard de la zone de visualisation 14.The hood 12 then has a simple opening opposite the zone of visualization 14.

La figure 2 présente le suceur vu de dessous. Ainsi la semelle 11 du suceur comporte plusieurs canaux d'aspiration : un canal 19 sensiblement parallèle au bord 6 du suceur, un canal 20 sensiblement parallèle au bord 5 du suceur. Ces canaux se rejoignent dans la région centrale 21 du suceur, proche de la zone de raccordement 32. Les canaux 19 et 20 possèdent des ouvertures frontales, c'est-à-dire dans les rebords verticaux de la semelle, respectivement 36 et 35, permettant une aspiration latérale sensiblement parallèle à la surface à nettoyer.Figure 2 shows the nozzle seen from below. So the sole 11 of nozzle has several suction channels: a channel 19 substantially parallel to the edge 6 of the nozzle, a channel 20 substantially parallel to the edge 5 of the nozzle. These channels meet in the central region 21 of the sucker, close of the connection zone 32. The channels 19 and 20 have openings front, that is to say in the vertical edges of the sole, respectively 36 and 35, allowing lateral suction substantially parallel to the surface to clean.

La forme triangulaire est complétée, à l'arrière du suceur, par une partie pleine 40 comportant deux fenêtres 42 au travers desquelles sont logés des moyens favorisant le déplacement du suceur, qui peuvent être, soit des patins de type PTFE, soit des roues.The triangular shape is completed, at the rear of the nozzle, by a part 40 with two windows 42 through which are housed means facilitating the displacement of the nozzle, which can be either skids PTFE type, or wheels.

Le suceur comporte par ailleurs une lame 23 s'étendant dans la région 21, du bord 5 du suceur au bord 6, en définissant ainsi un canal avant 18 et un canal arrière 22, le canal avant 18 débouchant à la pointe du suceur par l'ouverture 7 frontale. Cette lame 23 comporte une zone 24 où est disposé un tissu arrache-fils tel qu'il est en soi connu.The nozzle further comprises a blade 23 extending in the region 21, the edge 5 of the nozzle at the edge 6, thus defining a channel before 18 and a rear channel 22, the front channel 18 opening at the tip of the nozzle by the front opening 7. This blade 23 has a zone 24 where is disposed a pull-out fabric as it is known per se.

Cette lame 23 relie le bord 5 au bord 6 tel un pont, en ménageant un espace entre la face opposée à la zone 24 et la zone de visualisation 14. Cette lame est préférentiellement parallèle au bord arrière 9 du suceur.This blade 23 connects the edge 5 to the edge 6 as a bridge, leaving a space between the face opposite the zone 24 and the viewing zone 14. This blade is preferably parallel to the rear edge 9 of the nozzle.

Une seconde zone 124 portant un tissu arrache-fils peut être prévue sur une bordure du canal 22, de façon symétrique à la zone 24 portant l'arrache-fils.A second zone 124 carrying a pull-out fabric may be provided on a border of the channel 22, symmetrically to the zone 24 carrying the pull-son.

Les canaux 19 et 20 possèdent, chacun, des lames de raclage 46 et 45 s'étendant respectivement depuis le bord 6 et le bord 5 en direction de l'autre bord dans le canal d'aspiration. Selon l'exemple proposé, ces lames sont fixes et issues de la plaque inférieure du suceur en s'étendant sensiblement parallèlement au bord arrière 9 sur une distance voisine de la moitié de la largeur du canal. De préférence, ces lames sont légèrement proéminentes par rapport à la plaque inférieure du suceur.The channels 19 and 20 each have scraping blades 46 and 45 extending respectively from the edge 6 and the edge 5 towards the other edge in the suction channel. According to the proposed example, these blades are fixed and issuing from the bottom plate of the nozzle while extending substantially parallel to the rear edge 9 for a distance close to half of the width of the canal. Preferably, these blades are slightly prominent by compared to the bottom plate of the nozzle.

Selon l'exemple proposé, le suceur comporte également des brosses 55, 56, 57, lesdites brosses étant escamotables au travers de la semelle à l'aide d'un mécanisme 25 visible figure 3 et non décrit plus avant dans la présente demande. Sur cette figure sont également visibles les roues 43 montées sur une tige 44 et reliées aux conduits 30, 31, comme il sera expliqué ultérieurement.According to the proposed example, the nozzle also comprises brushes 55, 56, 57, said brushes being retractable through the sole using of a mechanism 25 visible in FIG. 3 and not further described herein. request. In this figure are also visible the wheels 43 mounted on a rod 44 and connected to the conduits 30, 31, as will be explained later.

Selon l'un des aspects de l'invention, les conduits 30, 31 sont articulés respectivement selon un axe x-x' et y-y', plus particulièrement visibles sur les figures 5 et 6. Ces axes sont sensiblement parallèles au bord arrière 9 du suceur. Le conduit 30 est articulé sur le conduit 31, lui même articulé sur la semelle du suceur.According to one aspect of the invention, the ducts 30, 31 are articulated respectively along an axis x-x 'and y-y', more particularly visible on the Figures 5 and 6. These axes are substantially parallel to the rear edge 9 of the nozzle. The conduit 30 is articulated on the conduit 31, itself articulated on the sole of the sucker.

Pour cela, le conduit 30 comporte deux parois latérales 300 dirigées vers le bas et dans lesquelles sont ménagés deux orifices 301 définissant l'axe x-x'. De façon similaire, le conduit 31 comporte deux orifices 311 situés en partie arrière dudit conduit, sur l'axe x-x', entre les orifices 301. L'axe x-x' est physiquement matérialisé par la tige 44 de support des roues 43, ces dernières étant montées à chaque extrémité de la tige 44.For this, the conduit 30 has two side walls 300 directed towards bottom and in which are formed two orifices 301 defining the axis x-x '. Similarly, the duct 31 has two orifices 311 located partly rear of said conduit, on the x-x 'axis, between the orifices 301. The x-x' axis is physically materialized by the rod 44 for supporting the wheels 43, the latter being mounted at each end of the rod 44.

Au niveau de la semelle du suceur, deux gorges 47 sont ménagées en bordure intérieure des passages 42 des roues afin de recevoir la tige 44. Ces gorges ne constituent que des points de repos de la tige 44 en position basse.At the level of the sole of the nozzle, two grooves 47 are formed in inner edge of the passages 42 of the wheels to receive the rod 44. These grooves are only rest points of the rod 44 in the low position.

Par ailleurs, le conduit 31 comporte, en partie avant, des ergots 312 définissant l'axe y-y'. En correspondance, la semelle 11 comporte des paliers 48 de réception des ergots 312, ces derniers étant emmanchés en force dans les paliers 48.Furthermore, the conduit 31 comprises, in the front part, pins 312 defining the y-y 'axis. In correspondence, the sole 11 comprises bearings 48 receiving pins 312, the latter being force-fitted into the bearings 48.

Ainsi, le conduit 31 est articulé, par les ergots 312, sur la semelle du suceur, sensiblement au voisinage du centre de gravité du suceur. Le conduit 30 est articulé sur le conduit 31 par l'intermédiaire de la tige 44, cette articulation étant flottante en suivant le mouvement de rotation du conduit 31 autour de son articulation. Les deux axes d'articulation sont situés à distance l'un de l'autre, cette distance résultant d'un compromis entre la maniabilité du suceur qui serait moindre si la distance était importante, et le manque d'intérêt par l'inefficacité d'une double articulation si la distance est trop faible. En pratique, une distance comprise entre 3 et 5 cm sépare les deux axes de rotation x-x' et y-y'.Thus, the conduit 31 is articulated, by the pins 312, on the sole of the sucker, substantially in the vicinity of the center of gravity of the nozzle. The conduit 30 is articulated on the conduit 31 via the rod 44, this articulation being floating following the rotational movement of the conduit 31 around his articulation. The two axes of articulation are located at a distance from each other, this distance resulting from a compromise between the maneuverability of the sucker that would be less if distance was important, and lack of interest by the inefficiency of a double articulation if the distance is too small. In practical, a distance between 3 and 5 cm separates the two axes of rotation x-x 'and y-y'.

Afin de garder une compacité importante du dispositif, la première tubulure 31 présente une longueur 1 relativement faible, inférieure à 5 cm, tel qu'il est représenté figure 8. Cette figure permet également de se rendre compte de l'agencement des tubulures, et notamment du recouvrement potentiel important de la tubulure 31 sur la tubulure 30 lors de son pivotement.In order to maintain a significant compactness of the device, the first tubing 31 has a relatively small length 1, less than 5 cm, such that it is represented figure 8. This figure also makes it possible to go account of the arrangement of the pipes, and in particular the covering large potential of the tubing 31 on the tubing 30 during its pivoting.

Les figures 8 et 9 présentent par ailleurs les positions extrêmes des différentes tubulures lors du maniement du suceur. Ainsi, figure 8, lorsque l'utilisateur déplace le suceur vers l'avant, il peut faire pivoter la tubulure 30 autour de l'axe x-x' matérialisé par la tige 44, ce pivotement pouvant se réaliser selon un angle α pouvant atteindre 35°. A cette valeur d'angle atteinte, la tubulure 30 bute contre une paroi verticale 310 faiblement prononcée sur l'enveloppe externe de la partie supérieure de la tubulure 31.Figures 8 and 9 also show the extreme positions of different tubings when handling the nozzle. So, figure 8, when the user moves the nozzle forward, it can rotate the tubing 30 around the axis x-x 'materialized by the rod 44, this pivoting being realized at an angle α of up to 35 °. At this angle value reached, the tubing 30 abuts against a vertical wall 310 weakly pronounced on the outer casing of the upper part of the tubular 31.

Ce premier pivotement permet notamment de garder le suceur bien en contact avec la surface à nettoyer lors de son déplacement vers l'avant, avec une latitude importante quant à la position angulaire des tubes de raccordement liés au suceur.This first pivot allows in particular to keep the nozzle well in contact with the surface to be cleaned when moving forward, with significant latitude with respect to the angular position of the tubes of connection related to the nozzle.

Durant toute la rotation de la tubulure 30 tel que précédemment décrit, les roues restent en contact avec le sol puisque la rotation s'effectue par rapport à l'axe des roues.During the entire rotation of the tubing 30 as previously described, the wheels remain in contact with the ground since the rotation is effected by relative to the axis of the wheels.

Depuis la position extrême précédemment décrite, l'utilisateur a la possibilité de redresser encore un peu plus la tubulure 30 entraínant, par son appui sur la paroi 310 de la tubulure 31, la rotation de cette dernière, tel qu'illustré figure 9. Cette rotation de la tubulure 31 se réalise autour de l'axe y-y' sur une valeur angulaire β pouvant atteindre 25°. Il résulte de cette rotation, un déplacement vertical des roues 43 selon une distance au plus égale à k. Cette distance est suffisante pour permettre aux roues d'être positionnées en retrait de la semelle 11.Since the extreme position described above, the user has the possibility of straightening a little more tubing 30 training, by his support on the wall 310 of the pipe 31, the rotation of the latter, such as illustrated in Figure 9. This rotation of the tubing 31 is made around the y-y 'axis on an angular value β of up to 25 °. It results from this rotation, a vertical displacement of the wheels 43 by a distance at most equal to k. This distance is sufficient to allow the wheels to be positioned withdrawal of sole 11.

Un tel suceur présente par ailleurs le phénomène remarquable suivant, en utilisation sur des sols de type moquette. Il est en effet connu que, pour ces types de revêtement, le passage de l'aspirateur est rendu fastidieux par la force nécessaire pour déplacer le suceur, ce dernier s'enfonçant dans les poils de la moquette et réduisant le flux d'air aspiré qui entraíne une augmentation locale de la dépression.Such a nozzle also has the following remarkable phenomenon, in use on carpeted floors. It is known that for these types of coating, vacuuming is made tedious by force necessary to move the nozzle, the latter sinking into the hairs of the carpet and reducing the flow of air sucked which leads to a local increase of depression.

Ce phénomène, connu, peut être compensé lors du déplacement du suceur vers l'avant par l'utilisateur où ce dernier peut utiliser son corps pour provoquer le déplacement du suceur. Toutefois, lorsque le suceur est déplacé vers l'arrière, c'est-à-dire lorsque l'utilisateur tire vers lui le suceur, la difficulté qu'il rencontre au déplacement du suceur provoque fréquemment un soulèvement de ce dernier, réduisant l'effet d'aspiration des poussières.This phenomenon, known, can be compensated during the displacement of the forward nozzle by the user where the latter can use his body for cause the nozzle to move. However, when the nozzle is moved towards the back, that is to say when the user pulls the nozzle, the difficulty that it encounters when moving the squeegee frequently causes a lifting of the latter, reducing the suction effect of the dust.

Or, par la présente invention, lorsque l'utilisateur déplace vers l'arrière le suceur, la dépression créée au niveau du sol tend à retenir le suceur. La résultante des forces entre cette retenue du suceur au sol et la traction exercée par l'utilisateur sur les tubes de liaison induit naturellement un pivotement des tubulures 30, 31 dans le sens horaire des figures 8 et 9, ce qui provoque une sortie des roues de la plaque de base formant la semelle. Cette sortie des roues permet au suceur de se déplacer plus facilement sur le sol.Now, by the present invention, when the user moves backwards the sucker, depression created at ground level tends to retain the nozzle. The resultant forces between this restraint of the nozzle on the ground and the traction exerted by the user on the connecting tubes naturally induces a pivoting of 30, 31 in the clockwise direction of FIGS. 8 and 9, which causes a wheel outlet from the base plate forming the sole. This output of wheels allows the nozzle to move more easily on the ground.

Ainsi, lorsque l'utilisateur déplace le suceur vers l'arrière en le tirant à lui, il provoque une sortie des roues qui viennent à son aide pour déplacer plus facilement le suceur.So, when the user moves the squeegee backwards by pulling it to him, it causes an output of the wheels that come to his aid to move more easily the nozzle.

Avantageusement, tel qu'illustré aux figures 10 à 12, une pièce de blocage 70 peut être ajoutée au suceur. Une telle pièce est localisée en arrière de l'articulation 30 et peut être actionnée par la pédale 8 lorsque l'utilisateur désire sortir les brosses. La figure 11 présente le suceur brosses escamotées, alors que la figure 12 présente le suceur brosses sorties.Advantageously, as illustrated in FIGS. 10 to 12, a piece of blocking 70 can be added to the nozzle. Such a room is located behind of the hinge 30 and can be actuated by the pedal 8 when the user want to take out the brushes. FIG. 11 shows the suction nozzle brushes retracted, while Figure 12 shows the nozzle brushes outlets.

Ainsi, lors de l'actionnement de la pédale 8 pour sortir les brosses, la pièce de blocage 70 passe sous l'articulation 30 de manière à venir bloquer les roues en position haute.Thus, when the pedal 8 is actuated to release the brushes, the blocking member 70 passes under the hinge 30 so as to block the wheels in high position.

En ce qui concerne le mécanisme de sortie des brosses, le lecteur pourra se référer à la demande française portant le numéro d'enregistrement FR 0307438 qui détaille ledit mécanisme de sortie des brosses tel que présenté. Dans le principe, la pédale 8, lorsqu'elle est actionnée pour faire sortir les brosses du suceur, fait pivoter une tige coudée 50 qui entraíne à son tour deux chariots mobiles horizontalement, ces derniers, par une surface de came inclinée lors de ce mouvement horizontal actionnent deux basculeurs portant les brosses, mobiles verticalement par rapport à la semelle, contre la force de rappel de deux ressorts.Regarding the mechanism of exit of the brushes, the reader may refer to the French application bearing the registration number FR 0307438 which details said brush outlet mechanism such as present. In principle, the pedal 8, when actuated to make remove the brushes from the nozzle, rotate an angled rod 50 which leads to its two horizontally movable trolleys, the latter, by a surface of inclined cam during this horizontal movement operate two rockers carrying the brushes, movable vertically in relation to the sole, against the return force of two springs.

On se sert donc ici de l'avancée de la tige coudée 50 lors de l'actionnement de la pédale pour faire avancer la pièce 70. A cette fin, la pièce 70 porte une échancrure 71 accueillant la tige 50.So we use here the advance of the bent rod 50 during actuation of the pedal to advance the piece 70. To this end, the piece 70 carries a notch 71 accommodating the rod 50.

La pièce 70 présente avantageusement une surface inclinée 72 dans sa partie frontale, permettant de déplacer les roues vers le haut lorsque ces dernières sont sorties. Il n'est donc pas nécessaire de positionner le tube 30 dans une position particulière, notamment celle, indiquée figure 9 où les roues sont relevées, afin de bloquer lesdites roues. Le blocage se réalise quelle que soit la position initiale de l'articulation.The part 70 advantageously has an inclined surface 72 in its front part, allowing the wheels to be moved upwards when these past are out. It is therefore not necessary to position the tube 30 in a particular position, in particular that indicated in FIG. 9 where the wheels are raised to lock said wheels. The blocking is realized whatever the initial position of the joint.

Ainsi, les roues ne touchant plus le sol, le suceur repose sur les brosses, favorisant, sur le type de sols concernés, c'est-à-dire les sols lisses, le déplacement latéral du suceur en empêchant les roues de frotter sur le sol lors du déplacement du suceur dans une direction qui ne correspond pas à la direction de roulement des roues.Thus, the wheels no longer touching the ground, the nozzle rests on the brushes, favoring, on the type of soil concerned, that is to say the smooth soils, the Lateral displacement of the squeegee by preventing the wheels from rubbing on the ground when moving the nozzle in a direction that does not correspond to the wheel running direction.

Ceci s'applique notamment lorsque l'on déplace le suceur le long des plinthes, puisque, par la forme triangulaire du suceur, la direction de roulement des roues se trouve inclinée par rapport à la direction de déplacement du suceur, ce qui provoque un frottement gênant lorsque les roues touchent le sol. Ceci est également valable pour un déplacement de gauche à droite sur sol lisse.This applies especially when we move the nozzle along the skirting, since, by the triangular shape of the nozzle, the rolling direction wheels are inclined relative to the direction of travel of the nozzle, which causes annoying friction when the wheels touch the ground. This is also valid for moving from left to right on ground smooth.

La double articulation avec sa particularité de sortie des roues est alors utilisée uniquement lorsque les brosses sont en position rentrée, principalement sur des sols de type moquette ou tapis où le déplacement du suceur est le plus difficile, en éliminant la composante verticale de poussée du suceur et en permettant à la semelle de s'adapter aux différentes moquettes et tapis.The double articulation with its particularity of exit of the wheels is then used only when the brushes are in the retracted position, mainly on carpeted or carpet type floors where the displacement of the nozzle is the most difficult, eliminating the vertical component of thrust of the nozzle and allowing the sole to adapt to different carpets and rugs.
