TECHNIQUE ANTERIEUREPRIOR ART
Un problème rencontré lors de l'utilisation d'un aspirateur provient des collisions entre le suceur de l'aspirateur et l'environnement de la surface à nettoyer. La répétition de ces collisions peut provoquer des dégâts importants sur les plinthes et les pieds des meubles et leurs rebords inférieurs par exemple ainsi que sur le suceur de l'aspirateur.A problem encountered when using a vacuum cleaner arises from collisions between the nozzle of the vacuum cleaner and the environment of the surface to be cleaned. The repetition of these collisions can cause significant damage to the baseboards and the feet of the furniture and their lower edges, for example, as well as to the nozzle of the vacuum cleaner.
Un des buts de l'invention est de résoudre le problème mentionné ci-dessus.One of the aims of the invention is to solve the problem mentioned above.
EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION
Selon l'invention, la semelle du suceur comporte un capot en matériau souple ou semi-rigide couvrant la face supérieure et les oords extérieurs de la semelle et destine à amortir les chocs provoqués par la collision du suceur avec l'environnement.According to the invention, the nozzle sole comprises a cover made of flexible or semi-rigid material covering the upper face and the outer edges of the sole and intended to absorb the shocks caused by the collision of the squeegee with the environment.
Un autre but de l'invention est de proposer un suceur présentant une structure compacte, et notamment au niveau de sa hauteur, le but premier de l'invention trouvant tout son intérêt lorsque le suceur est de faible hauteur, puisqu'il peut alors être passé sous les meubles, lits,... sans risque pour le mobilier.Another object of the invention is to provide a nozzle having a compact structure, and in particular at the level of its height, the primary object of the invention finding all its advantage when the nozzle is of low height, since it can then be passed under furniture, beds, ... without risk for furniture.
L'invention est atteinte à l'aide d'un suceur d' aspirateur comportant une semelle comprenant au moins une partie du circuit de circulation d'air, raccordé, de façon amovible, à un tube d'évacuation des déchets aspirés, et un capot couvrant la face supérieure et les bords extérieurs de la semelle, caractérisé en ce que des éléments sont agencés sur la semelle afin de fermer le circuit de circulation d'air jusqu'au tube, et en ce que le capot est en matériau souple ou semi-rigide.The invention is achieved using a vacuum cleaner nozzle comprising a soleplate comprising at least part of the air circulation circuit, connected, in a removable manner, to a tube for evacuating the aspirated waste, and a cover covering the upper face and the outer edges of the sole, characterized in that elements are arranged on the sole in order to close the air circulation circuit up to the tube, and in that the cover is made of flexible material or semi-rigid.
Avantageusement, la dureté Vickers du capot est comprise entre 25 et 90 Shores A, assurant au suceur de ne pas endommager la plupart des éléments mobiliers susceptibles de se trouver à l'intérieur d'une maison.Advantageously, the Vickers hardness of the hood is between 25 and 90 Shores A, ensuring that the squeegee does not damage most of the movable elements likely to be inside a house.

MEILLEURE MANIERE DE REALISER L'INVENTIONBEST WAY TO IMPLEMENT THE INVENTION
La figure 1 permet de visualiser le capot 17 du suceur 1 qui couvre la majeure partie de la structure interne du suceur, exceptée l'articulation 11 du suceur 1 au tube 16 d'évacuation. Dans une variante de réalisation, le capot 17 comporte plusieurs ouvertures 5, 7 coïncidant avec les ouvertures pratiquées 13, 12 au niveau de la semelle 4 dans le circuit d'aspiration. Par ailleurs, les angles sont arrondis, notamment au niveau de la pointe 6 avant du suceur afin de ne pas endommager l'environnement. On peut se faire une idée précise de la forme du capot en comparant les figures 1 et 3 puisque cette dernière présente le suceur sans capot.Figure 1 shows the cover 17 of the nozzle 1 which covers most of the internal structure of the nozzle, except the articulation 11 of the nozzle 1 to the discharge tube 16. In an alternative embodiment, the cover 17 has several openings 5, 7 coinciding with the openings 13, 12 at the level of the sole 4 in the suction circuit. Furthermore, the angles are rounded, in particular at the level of the tip 6 before the nozzle so as not to damage the environment. We can get a precise idea of the shape of the cover by comparing Figures 1 and 3 since the latter presents the nozzle without cover.
Sur la figure 2 est présentée la semelle 4 destinée à se déplacer sur la surface à nettoyer, le rebord de ladite semelle présente une zone angulaire 6 munie d' une ouverture d'aspiration frontale 12 et dont l'extrémité est arrondie afin d'éviter de détériorer les murs et les meubles lors du déplacement du suceur 1. La face inférieure du suceur est munie de trois patins amovibles 10 permettant au suceur 1 de glisser sur la surface à nettoyer.In FIG. 2 is shown the sole 4 intended to move over the surface to be cleaned, the edge of said sole has an angular zone 6 provided with a front suction opening 12 and the end of which is rounded in order to avoid damaging the walls and the furniture during the movement of the nozzle 1. The underside of the nozzle is provided with three removable pads 10 allowing the nozzle 1 to slide on the surface to be cleaned.
Comme il est clairement visible sur les figures 3 et 4, la face supérieure de la semelle 4 est munie d'un circuit de circulation d'air 8. Ce dernier présente une forme en H ayant une gorge centrale 40 dans laquelle est monté le conduit 42 constituant la barre horizontale d'une connexion en T 11 et deux gorges latérales 44 reliant chacun des deux orifices inférieurs 14 situés le long du canal postérieur 27 à l'un des deux orifices inférieurs 14 situés le long de l'un des canaux latéraux 26.As is clearly visible in Figures 3 and 4, the upper face of the sole 4 is provided with an air circulation circuit 8. The latter has an H shape having a central groove 40 in which the duct is mounted 42 constituting the horizontal bar of a T connection 11 and two lateral grooves 44 connecting each of the two lower orifices 14 located along the posterior channel 27 to one of the two lower orifices 14 located along one of the lateral channels 26.
La connexion en T 11, montée de façon amovible sur la face supérieure de ladite semelle 4, permet de relier, via ledit circuit de circulation d'air 8, une pluralité d'ouvertures d'aspiration (12,13,14) à un tube amovible 16 d'évacuation des déchets aspirés.The T connection 11, removably mounted on the upper face of said sole 4, makes it possible to connect, via said air circulation circuit 8, a plurality of suction openings (12,13,14) to a removable tube 16 for evacuating the aspirated waste.
Les gorges latérales 44 du circuit de circulation d' air 8 sont couvertes à leurs extrémités par un premier couvercle 50 de forme plate et à leur milieu par un deuxième couvercle 52 de forme semi-cylindrique prolongeant le conduit 42 de la connexion en T 11.The lateral grooves 44 of the air circulation circuit 8 are covered at their ends by a first cover 50 of flat shape and in their middle by a second cover 52 of semi-cylindrical shape extending the conduit 42 of the T connection 11.
Ainsi, le suceur présente une forme compacte par la délimitation du conduit d'aération par une structure de type canalisation. La définition d'un tel conduit aéraulique, reliant les ouvertures d'aspiration du suceur au conduit d'évacuation, permet la suppression du capot jouant ce rôle de fermeture du conduit d'aspiration.Thus, the nozzle has a compact shape by the delimitation of the ventilation duct by a structure of the pipe type. The definition of such an air duct, connecting the suction openings of the squeegee to the exhaust duct, allows the removal of the cover playing this role of closing the suction duct.
Le suceur présente ainsi une forme aplatie, de faible hauteur, auquel peut donc être joint un capot souple ou semi-rigide de protection, sans que ce dernier apparaisse comme un élément rapporte induisant un volume plus important du suceur. L'encombrement d'un tel suceur est ainsi réduit.The squeegee thus has a flattened shape, of low height, to which a flexible or semi-rigid protective cover can therefore be attached, without the latter appears as a related element inducing a larger volume of the nozzle. The size of such a nozzle is thus reduced.
Par ailleurs, le fait d'avoir fermé le conduit de circulation d'air par une structure rigide garantit un bon fonctionnement du suceur, même s'il arrivait que le capot soit endommagé par un élément extérieur.Furthermore, the fact of having closed the air circulation duct by a rigid structure guarantees correct operation of the nozzle, even if the hood were damaged by an external element.
Selon une autre caractéristique de l'invention, chacune des gorges latérales 44 du circuit en H comporte un déflecteur latéral 60 situé à proximité de la zone rencontre des flux d'air entrant par les ouvertures d'aspiration 14 se faisant face. La connexion en T 11 comporte également, comme on peut le voir sur les figures 3 et 5, un déflecteur central 62 destiné à éviter une collision frontale entre les flux d'air circulant dans le conduit 42.According to another characteristic of the invention, each of the lateral grooves 44 of the H-shaped circuit comprises a lateral deflector 60 located near the zone where air flows entering through the suction openings 14 facing each other meet. The connection at T 11 also includes, as can be seen in FIGS. 3 and 5, a central deflector 62 intended to avoid a frontal collision between the air flows circulating in the duct 42.
Selon une caractéristique importante de l'invention, ladite semelle 4 comporte un capot amovible 17 en matériau souple ou semi-rigide destiné a amortir les chocs provoques par la collision du suceur 1 avec l'environnement le long des plinthes ou meubles aussi bien qu'en dessous de ces meubles. Les matériaux utilises pour la réalisation du capot peuvent provenir de diverses formulations et/ou mélanges. Il peut s'agir de caoutchouc thermoplastique, couramment dénommes TPE, en association avec du polypropylène, ou une composition à base de polyuréthanne et de polyester, en différentes proportions.According to an important characteristic of the invention, said sole 4 comprises a removable cover 17 made of flexible or semi-rigid material intended to absorb the shocks caused by the collision of the nozzle 1 with the environment along the baseboards or furniture as well as below this furniture. The materials used for the production of the cover can come from various formulations and / or mixtures. It can be thermoplastic rubber, commonly called TPE, in combination with polypropylene, or a composition based on polyurethane and polyester, in different proportions.
Selon une caractéristique générale des matériaux utilisés, la dureté Shores du capot est comprise entre 25 et 90 Shores A, selon le test généralement employé pour caractérise les matériaux de type plastique.According to a general characteristic of the materials used, the hardness Shores of the cover is between 25 and 90 Shores A, according to the test generally used to characterize plastic materials.
Selon une variante de réalisation, le capot est réalise en elastomère. Selon un mode préféré de réalisation de l'invention, la semelle 4 présente une forme sensiblement triangulaire dont les deux côtés adjacents 24 comportent chacun un canal latéral 26 ouvert vers la surface à nettoyer, agencé le long du rebord de la semelle. Chacun desdits canaux latéraux 26 est relié, au moyen d'un coude 28 ouvert vers la surface à nettoyer, à un canal postérieur 27 ouvert vers la surface à nettoyer agencé le long du troisième côté 30 formant la face postérieure de la semelle 4. Les coudes 28 sont sensiblement perpendiculaires audit côté 30 et comportent chacun au moins un orifice latéral d'aspiration 13.According to an alternative embodiment, the cover is made of elastomer. According to a preferred embodiment of the invention, the sole 4 has a substantially triangular shape, the two adjacent sides 24 each having a lateral channel 26 open towards the surface to be cleaned, arranged along the edge of the sole. Each of said lateral channels 26 is connected, by means of an elbow 28 open to the surface to be cleaned, to a posterior channel 27 open to the surface to be cleaned arranged along the third side 30 forming the rear face of the sole 4. The elbows 28 are substantially perpendicular to said side 30 and each comprise at least one lateral suction orifice 13.
Selon un mode particulier de réalisation, les canaux 26 et 27 présentent une forme tubulaire et chacun desdits canaux 26 comporte un orifice inférieur 14 tandis que le canal 27 comporte deux orifices inférieurs 14 situés symétriquement par rapport au milieu dudit côté postérieur 30. Ces orifices inférieurs 14 sont destinés à assurer une aspiration des déchets dans une direction perpendiculaire à la surface à nettoyer.According to a particular embodiment, the channels 26 and 27 have a tubular shape and each of said channels 26 has a lower orifice 14 while the channel 27 has two lower orifices 14 located symmetrically with respect to the middle of said rear side 30. These lower orifices 14 are intended to ensure a suction of the waste in a direction perpendicular to the surface to be cleaned.
Selon une autre caractéristique du suceur conforme à l'invention, la semelle 4 est reliée à la connexion en T 11 par une articulation 70 permettant d'assurer, d'une part, une rotation complète de la semelle 4 par rapport au tube 16, et d'autre part, un pivotement dudit tube 16 au dessus de ladite semelle 4 d'un angle de 180° autour d'un axe horizontal 72 confondu avec l'axe de symétrie du conduit 42 formant la barre horizontale de la connexion en T 11.According to another characteristic of the nozzle according to the invention, the sole 4 is connected to the T-connection 11 by a hinge 70 making it possible, on the one hand, to ensure complete rotation of the sole 4 relative to the tube 16, and on the other hand, a pivoting of said tube 16 above said sole 4 by an angle of 180 ° around a horizontal axis 72 coincident with the axis of symmetry of the conduit 42 forming the horizontal bar of the T-connection 11.
Ceci permet à l'utilisateur de pouvoir présenter deux bords d'attaque différents lors de l'utilisation de l'aspirateur, soit un bord d'attaque droit pour l'usage classique du suceur, soit un bord d'attaque en forme de pointe, pour notamment aspirer dans les coins. Par ailleurs, sur cette figure sont également visibles les éléments de connexion 51 de type femelle pouvant coopérer avec des éléments complémentaires mâles situés sur la face interne du capot afin de fixer celui-ci sur la semelle 4.This allows the user to be able to present two different leading edges when using the vacuum cleaner, either a straight leading edge for conventional use of the nozzle, or a leading edge in the shape of a tip. , in particular to vacuum in the corners. Furthermore, in this figure are also visible the female-type connection elements 51 which can cooperate with complementary male elements located on the internal face of the cover in order to fix the latter on the sole 4.
Afin d'assurer un déplacement par glissement du suceur sur des surfaces de différents types, les patins amovibles 10, représentés schématiquement à la figure 6, comportent une face inférieure 80, ayant un bord d'attaque arrondi 82, et sont munis d'une pastille centrale 84 assurant le contact avec la surface à nettoyer lors du déplacement de l'appareil. Ladite pastille centrale 84 peut être en PTFE ou en tout autre matériau ayant une bonne résistance à l'abrasion et un faible coefficient de frottement. La face supérieure 86 des patins de glissement 10 comporte une couronne centrale 88 entourée par un joint annulaire 90 destiné à absorber les vibrations lorsque le suceur se déplace sur une surface accidentée. Lesdits patins 10 peuvent être montés aussi bien sur un traîneau d' aspirateur que sur un nettoyeur à vapeur sans sortir du cadre de l'invention.In order to ensure a sliding movement of the nozzle on surfaces of different types, the removable pads 10, shown diagrammatically in FIG. 6, have a lower face 80, having a rounded leading edge 82, and are provided with a central pad 84 ensuring contact with the surface to be cleaned when moving the device. Said central pad 84 may be made of PTFE or any other material having good abrasion resistance and a low coefficient of friction. The upper face 86 of the sliding shoes 10 has a central ring 88 surrounded by an annular seal 90 intended to absorb vibrations when the nozzle moves on an uneven surface.
