Description

Domaine techniqueTechnical area

La présente invention concerne le domaine des aspirateurs équipés d'un suceur d'aspirateur, également nommé tête de succion, permettant d'aspirer des poussières et des déchets présents sur une surface à nettoyer, qui peut par exemple être du carrelage, du parquet, du stratifié, de la moquette ou un tapis.The present invention relates to the field of vacuum cleaners equipped with a vacuum cleaner nozzle, also called a suction head, making it possible to suck up dust and waste present on a surface to be cleaned, which can for example be tiles, parquet, laminate, carpet or rug.

Etat de la techniqueState of the art

Le document FR3062562 divulgue un suceur d'aspirateur comprenant :

  • une semelle munie d'une face inférieure et d'une cavité d'aspiration débouchant sur la face inférieure,
  • une fourche montée articulée sur la semelle par l'intermédiaire d'une liaison pivot avant définissant un axe de pivotement avant qui s'étend transversalement à une direction de déplacement du suceur d'aspirateur,
  • deux roues principales destinées à rouler sur une surface à nettoyer, les deux roues principales étant montées mobiles en rotation sur la fourche autour d'un axe de roue qui est sensiblement parallèle à l'axe de pivotement avant, et
  • un manchon de raccordement relié fluidiquement à la cavité d'aspiration.
The document FR3062562 discloses a vacuum cleaner nozzle comprising:
  • a sole provided with a lower face and a suction cavity opening onto the lower face,
  • a fork mounted articulated on the sole via a front pivot connection defining a front pivot axis which extends transversely to a direction of movement of the vacuum cleaner nozzle,
  • two main wheels intended to roll on a surface to be cleaned, the two main wheels being mounted movable in rotation on the fork around a wheel axis which is substantially parallel to the front pivot axis, and
  • a connection sleeve fluidly connected to the suction cavity.

Le manchon de raccordement comporte plus particulièrement une première partie de manchon montée articulée sur la fourche par l'intermédiaire d'une liaison pivot arrière définissant un axe de pivotement arrière qui s'étend parallèlement à l'axe de pivotement avant, et une deuxième partie de manchon à laquelle est destiné à être fixé un tube d'aspiration d'un aspirateur.The connection sleeve comprises more particularly a first sleeve part mounted articulated on the fork via a rear pivot connection defining a rear pivot axis which extends parallel to the front pivot axis, and a second part sleeve to which a suction tube of a vacuum cleaner is intended to be attached.

Les première et deuxième parties de manchon sont montées mobiles en rotation l'une par rapport autour d'un axe de rotation qui est perpendiculaire aux axes de pivotement avant et arrière. Une telle configuration du manchon de raccordement permet notamment d'améliorer la maniabilité d'un tube d'aspiration fixé au manchon de raccordement, et donc la maniabilité du suceur d'aspirateur précité.The first and second sleeve parts are mounted movable in rotation relative to one another around an axis of rotation which is perpendicular to the front and rear pivot axes. Such a configuration of the connection sleeve makes it possible in particular to improve the handling of a suction tube fixed to the connection sleeve, and therefore the handling of the aforementioned vacuum cleaner nozzle.

Toutefois, lorsqu'un utilisateur souhaite aspirer des déchets par exemple sous un meuble ou un lit avec un aspirateur équipé d'un tel suceur, un pivotement vers l'arrière du manchon de raccordement, et donc du tube d'aspiration, est limité du fait que la première partie de manchon vient rapidement en contact avec la surface à nettoyer. Ainsi, du fait de l'encombrement en hauteur important du suceur précité, ce dernier suceur précité ne permet pas de pouvoir aisément aspirer des déchets situés sous des meubles ou des lits.However, when a user wishes to vacuum up waste, for example under furniture or a bed with a vacuum cleaner equipped with such a nozzle, rearward pivoting of the connection sleeve, and therefore of the suction tube, is limited. causes the first sleeve part to quickly come into contact with the surface to be cleaned. Thus, due to the significant height of the aforementioned nozzle, the latter aforementioned nozzle does not make it possible to easily vacuum up waste located under furniture or beds.

De plus, un tel pivotement vers l'arrière du manchon de raccordement est susceptible, en raison de la masse du tube d'aspiration qui est appliquée sur la fourche, d'induire un soulèvement d'une partie avant de la face inférieure de la semelle, ce qui est préjudiciable à la qualité d'aspiration du suceur.Furthermore, such rearward pivoting of the connection sleeve is likely, due to the mass of the suction tube which is applied to the fork, to induce a lifting of a front part of the lower face of the sole, which is detrimental to the suction quality of the nozzle.

Résumé de l'inventionSummary of the invention

La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these drawbacks.

Le problème technique à la base de l'invention consiste notamment à fournir un suceur d'aspirateur qui soit de structure simple et économique, tout en permettant une aspiration efficace et aisée notamment sous des meubles ou des lits.The technical problem underlying the invention consists in particular of providing a vacuum cleaner nozzle which is simple and economical in structure, while allowing efficient and easy suction, particularly under furniture or beds.

A cet effet, l'invention a pour objet un suceur d'aspirateur comprenant :

  • une semelle munie d'une face inférieure et d'une cavité d'aspiration débouchant sur la face inférieure,
  • une fourche montée articulée sur la semelle par l'intermédiaire d'une liaison pivot avant définissant un axe de pivotement avant qui s'étend transversalement à une direction de déplacement du suceur d'aspirateur,
  • deux roues principales destinées à rouler sur une surface à nettoyer, les deux roues principales étant montées mobiles en rotation sur la fourche autour d'un axe de roue qui est sensiblement parallèle à l'axe de pivotement avant, et
  • un manchon de raccordement auquel est destiné à être fixé un tube d'aspiration d'un aspirateur, le manchon de raccordement étant relié fluidiquement à la cavité d'aspiration.
For this purpose, the invention relates to a vacuum cleaner nozzle comprising:
  • a sole provided with a lower face and a suction cavity opening onto the lower face,
  • a fork mounted articulated on the sole via a front pivot connection defining a front pivot axis which extends transversely to a direction of movement of the vacuum cleaner nozzle,
  • two main wheels intended to roll on a surface to be cleaned, the two main wheels being mounted movable in rotation on the fork around a wheel axis which is substantially parallel to the front pivot axis, and
  • a connection sleeve to which a suction tube of a vacuum cleaner is intended to be attached, the connection sleeve being fluidly connected to the suction cavity.

Le suceur d'aspirateur comporte en outre un organe de liaison reliant mécaniquement le manchon de raccordement à la fourche, l'organe de liaison étant monté articulé sur la fourche par l'intermédiaire d'une liaison pivot centrale définissant un axe de rotation qui s'étend transversalement à l'axe de pivotement avant, et l'axe de roue est sécant avec l'organe de liaison.The vacuum cleaner nozzle further comprises a connecting member mechanically connecting the connection sleeve to the fork, the connecting member being hingedly mounted on the fork via a central pivot connection defining an axis of rotation which 'extends transversely to the front pivot axis, and the wheel axis intersects with the connecting member.

Une telle configuration de l'organe de liaison et une telle disposition de la liaison pivot centrale permettent de réduire l'encombrement en hauteur du suceur d'aspirateur lorsqu'un tube d'aspiration fixé au manchon de raccordement est positionné sensiblement horizontalement et à proximité de la surface à nettoyer, et donc de déplacer aisément le suceur d'aspirateur sous des meubles ou des lits.Such a configuration of the connecting member and such an arrangement of the central pivot connection make it possible to reduce the height of the vacuum cleaner nozzle when a suction tube fixed to the connection sleeve is positioned substantially horizontally and close to of the surface to be cleaned, and therefore easily move the vacuum cleaner nozzle under furniture or beds.

Une telle configuration de la liaison pivot centrale, associée au montage des roues principales sur la fourche, permet également d'éviter un soulèvement des roues principales lors d'un virage du suceur d'aspiration induit par l'application par l'utilisateur d'un couple sur le tube d'aspiration et/ou par une inclinaison latérale du tube d'aspiration. Ces dispositions permettent ainsi d'assurer un efficacité d'aspiration améliorée.Such a configuration of the central pivot connection, associated with the mounting of the main wheels on the fork, also makes it possible to avoid lifting of the main wheels during a turn of the suction nozzle induced by the application by the user of a torque on the suction tube and/or by a lateral inclination of the suction tube. These arrangements thus make it possible to ensure improved suction efficiency.

De plus, le fait que l'axe de roue soit sécant avec l'organe de liaison permet d'améliorer la stabilité du suceur d'aspirateur selon la présente invention.In addition, the fact that the wheel axle intersects with the connecting member makes it possible to improve the stability of the vacuum cleaner nozzle according to the present invention.

Le suceur d'aspirateur peut en outre présenter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison.The vacuum nozzle may also have one or more of the following characteristics, taken alone or in combination.

Selon un mode de réalisation de l'invention, la liaison pivot centrale est située entre la liaison pivot avant et l'axe de roue. Une telle disposition de la liaison centrale permet d'éviter un soulèvement d'une partie avant de la face inférieure de la semelle lorsque qu'un tube d'aspiration fixé au manchon de raccordement est pivoté vers l'arrière, et donc d'assurer une efficacité d'aspiration optimale également lors de l'aspiration de déchets situés sous un meuble ou un lit. De plus, une telle disposition de la liaison centrale permet de mieux répartir sur le suceur l'effort vertical induit par la masse du tube d'aspiration, et en particulier d'éviter que cet effort vertical soit appliqué directement sur les roues principales.According to one embodiment of the invention, the central pivot connection is located between the front pivot connection and the wheel axle. Such an arrangement of the central connection makes it possible to avoid lifting of a front part of the lower face of the sole when a suction tube fixed to the connection sleeve is pivoted towards the rear, and therefore to ensure Optimal suction efficiency also when vacuuming waste located under furniture or a bed. In addition, such an arrangement of the central connection makes it possible to better distribute the vertical force induced by the mass of the suction tube on the squeegee, and in particular to prevent this vertical force from being applied directly to the main wheels.

Selon un mode de réalisation de l'invention, l'axe de rotation est sensiblement perpendiculaire à l'axe de pivotement avant.According to one embodiment of the invention, the axis of rotation is substantially perpendicular to the front pivot axis.

Selon un mode de réalisation de l'invention, lorsque les deux roues principales du suceur d'aspirateur reposent sur une surface horizontale, l'axe de rotation est sensiblement horizontal ou est incliné par rapport à la surface horizontale d'un angle d'inclinaison inférieur à 10°, et par exemple inférieure à 5°. Ces dispositions permettent de faciliter les déplacements du suceur lorsque l'utilisateur exerce une force de poussée sur le suceur via un tube d'aspiration fixé au manchon de raccordement, et ce sans nuire à l'efficacité d'aspiration du suceur.According to one embodiment of the invention, when the two main wheels of the vacuum cleaner nozzle rest on a horizontal surface, the axis of rotation is substantially horizontal or is inclined relative to the horizontal surface by an angle of inclination less than 10°, and for example less than 5°. These arrangements make it easier to move the nozzle when the user exerts a pushing force on the nozzle via a suction tube fixed to the connecting sleeve, without harming the suction efficiency of the nozzle.

Selon un mode de réalisation de l'invention, un plan passant par l'axe de pivotement avant et par l'axe de roue est sécant avec l'organe de liaison. Ces dispositions permettent de diminuer encore l'encombrement en hauteur du suceur d'aspirateur selon l'invention.According to one embodiment of the invention, a plane passing through the front pivot axis and through the wheel axle intersects with the connecting member. These arrangements make it possible to further reduce the height of the vacuum cleaner nozzle according to the invention.

Selon un mode de réalisation de l'invention, le manchon de raccordement est monté articulé sur l'organe de liaison par l'intermédiaire d'une liaison pivot arrière définissant un axe de pivotement arrière qui est sensiblement parallèle à l'axe de pivotement avant.According to one embodiment of the invention, the connection sleeve is mounted articulated on the connecting member via a rear pivot connection defining a rear pivot axis which is substantially parallel to the front pivot axis .

Selon un mode de réalisation de l'invention, la liaison pivot centrale est située entre la liaison pivot arrière et la liaison pivot avant. Une telle disposition de la liaison pivot permet d'éviter de réaliser le manchon de raccordement sous forme de coude rigide (cette forme coudée réside alors par exemple dans un conduit de liaison flexible reliant fluidiquement le manchon de raccordement à la cavité d'aspiration), et donc de pouvoir positionner le manchon de raccordement sensiblement horizontalement pour aspirer aisément des déchets sous des meubles.According to one embodiment of the invention, the central pivot connection is located between the rear pivot link and the front pivot link. Such an arrangement of the pivot connection makes it possible to avoid making the connection sleeve in the form of a rigid elbow (this elbow shape then resides for example in a flexible connection conduit fluidly connecting the connection sleeve to the suction cavity), and therefore to be able to position the connection sleeve substantially horizontally to easily vacuum up waste under furniture.

Selon un mode de réalisation de l'invention, un plan passant par l'axe de pivotement avant et par l'axe de pivotement arrière est sécant avec l'organe de liaison. Ces dispositions permettent de diminuer encore l'encombrement en hauteur du suceur d'aspirateur selon l'invention.According to one embodiment of the invention, a plane passing through the front pivot axis and the rear pivot axis intersects with the connecting member. These arrangements make it possible to further reduce the height of the vacuum cleaner nozzle according to the invention.

Selon un mode de réalisation de l'invention, lorsque les deux roues principales du suceur d'aspirateur reposent sur une surface horizontale, la distance entre l'axe de pivotement arrière et la surface horizontale est sensiblement identique ou supérieure à la distance entre l'axe de roue et la surface horizontale.According to one embodiment of the invention, when the two main wheels of the vacuum cleaner nozzle rest on a horizontal surface, the distance between the rear pivot axis and the horizontal surface is substantially identical to or greater than the distance between the wheel axle and the horizontal surface.

Selon un mode de réalisation de l'invention, l'axe de pivotement arrière correspond sensiblement à l'axe de roue.According to one embodiment of the invention, the rear pivot axis corresponds substantially to the wheel axis.

Selon un mode de réalisation de l'invention, l'axe de pivotement arrière est décalé vers l'arrière vis-à-vis de l'axe de roue. Une telle disposition de l'axe de pivotement arrière améliore encore la stabilité du suceur d'aspirateur selon la présente invention.According to one embodiment of the invention, the rear pivot axis is offset rearwardly with respect to the wheel axis. Such an arrangement of the rear pivot axis further improves the stability of the vacuum cleaner nozzle according to the present invention.

Selon un mode de réalisation de l'invention, la fourche comporte deux bras de fourche montés articulés sur la semelle par l'intermédiaire de la liaison pivot avant, et une partie de liaison reliant les deux bras de fourche l'un à l'autre et s'étendant transversalement aux bras de fourche.According to one embodiment of the invention, the fork comprises two fork arms mounted articulated on the sole via the front pivot connection, and a connecting part connecting the two fork arms to each other. and extending transversely to the fork arms.

Selon un mode de réalisation de l'invention, chacun des bras de fourche s'étend sensiblement parallèlement à la direction de déplacement du suceur d'aspirateur.According to one embodiment of the invention, each of the fork arms extends substantially parallel to the direction of movement of the nozzle vacuum cleaner.

Selon un mode de réalisation de l'invention, la partie de liaison s'étend en dessous de l'organe de liaison. Ces dispositions permettent d'une part de diminuer encore l'encombrement en hauteur du suceur d'aspirateur selon l'invention, et d'autre part de permettre à la fourche de supporter et répartir les efforts de torsion dus aux mouvements de rotation gauche/droite.According to one embodiment of the invention, the connecting part extends below the connecting member. These arrangements make it possible on the one hand to further reduce the height of the vacuum cleaner nozzle according to the invention, and on the other hand to allow the fork to support and distribute the torsional forces due to left/left rotational movements. RIGHT.

Selon un mode de réalisation de l'invention, chacun des bras de fourche comporte une extrémité libre, les extrémités libres des deux bras de fourche comportant respectivement deux ergots qui sont sensiblement coaxiaux et qui font saillie dans une direction transversale aux bras de fourche, les deux ergots formant en partie la liaison pivot avant.According to one embodiment of the invention, each of the fork arms has a free end, the free ends of the two fork arms respectively comprising two lugs which are substantially coaxial and which project in a direction transverse to the fork arms, the two lugs partly forming the front pivot connection.

Selon un mode de réalisation de l'invention, la liaison pivot centrale est disposée entre les deux bras de fourche. Ces dispositions permettent de diminuer encore l'encombrement en hauteur du suceur d'aspirateur selon l'invention.According to one embodiment of the invention, the central pivot connection is arranged between the two fork arms. These arrangements make it possible to further reduce the height of the vacuum cleaner nozzle according to the invention.

Selon un mode de réalisation de l'invention, l'organe de liaison comporte une partie de montage qui est annulaire et qui est montée mobile en rotation sur la fourche autour de l'axe de rotation.According to one embodiment of the invention, the connecting member comprises a mounting part which is annular and which is mounted to move in rotation on the fork around the axis of rotation.

Selon un mode de réalisation de l'invention, la distance entre la partie de montage et l'axe de pivotement arrière est plus petite que la distance entre la partie de montage et l'axe de pivotement avant. Ces dispositions permettent de répartir la masse du tube d'aspiration plus sur les roues principales que sur la semelle, et donc d'éviter que la semelle ne s'enfonce trop sur un sol mou de type moquette.According to one embodiment of the invention, the distance between the mounting part and the rear pivot axis is smaller than the distance between the mounting part and the front pivot axis.

Seuls les éléments nécessaires à la compréhension de l'invention sont représentés. Pour faciliter la lecture des dessins, les mêmes éléments portent les mêmes références d'une figure à l'autre.Only the elements necessary for understanding the invention are represented. To make the drawings easier to read, the same elements carry the same references from one figure to another.

Les figures 1 à 7 représentent un suceur d'aspirateur 2 comprenant une semelle 3 munie d'une face inférieure 4 destinée à être positionnée de manière attenante à la surface à aspirer durant l'utilisation du suceur d'aspirateur 2.THE figures 1 to 7 represent a vacuum cleaner nozzle 2 comprising a sole 3 provided with a lower face 4 intended to be positioned adjacent to the surface to be vacuumed during use of the vacuum cleaner nozzle 2.

La semelle 3 est également munie d'une cavité d'aspiration 5 débouchant sur la face inférieure 4. De façon avantageuse, la cavité d'aspiration 5 est allongée et s'étend selon une direction d'extension D1 qui est transversale à une direction de déplacement D2 du suceur d'aspirateur 2, et par exemple perpendiculaire à la direction de déplacement D2.The sole 3 is also provided with a suction cavity 5 opening onto the lower face 4. Advantageously, the suction cavity 5 is elongated and extends in a direction of extension D1 which is transverse to a direction displacement D2 of the vacuum cleaner nozzle 2, and for example perpendicular to the direction of movement D2.

Le suceur d'aspirateur 2 comprend en outre une fourche 6 comportant deux bras de fourche 7 et une partie de liaison 8 qui relie les deux bras de fourche 7 l'un à l'autre et qui s'étend transversalement aux bras de fourche 7. Chacun des bras de fourche 7 s'étend par exemple sensiblement parallèlement à la direction de déplacement D2 du suceur d'aspirateur 2 et comporte une extrémité libre. Cependant, les bras de fourche 7 pourrait être légèrement inclinés l'un par rapport à l'autre, et par exemple divergés en direction de la semelle 3.The vacuum cleaner nozzle 2 further comprises a fork 6 comprising two fork arms 7 and a connecting part 8 which connects the two fork arms 7 to each other and which extends transversely to the fork arms 7 Each of the fork arms 7 extends for example substantially parallel to the direction of movement D2 of the vacuum cleaner nozzle 2 and has a free end. However, the fork arms 7 could be slightly inclined relative to each other, and for example diverged towards the sole 3.

Les deux bras de fourche 7 sont montés articulés sur la semelle 3 par l'intermédiaire d'une liaison pivot avant P1 définissant un axe de pivotement avant X1 qui s'étend perpendiculairement à la direction de déplacement D2 du suceur d'aspirateur 2 et qui est sensiblement horizontal lorsque le suceur d'aspirateur repose sur une surface horizontale. Ainsi, la fourche 6 peut basculer vers l'arrière ou vers l'avant par rapport à la semelle 3, comme l'illustrent respectivement les flèches F1 et F2 sur la figure 6.The two fork arms 7 are mounted articulated on the sole 3 via a front pivot connection P1 defining a front pivot axis X1 which extends perpendicular to the direction of movement D2 of the vacuum cleaner nozzle 2 and which is substantially horizontal when the vacuum cleaner nozzle rests on a horizontal surface. Thus, the fork 6 can tilt backwards or forwards relative to the sole 3, as illustrated respectively by arrows F1 and F2 on the Figure 6 .

Selon le mode de réalisation représenté sur les figures, les extrémités libres des deux bras de fourche 7 comportent respectivement deux ergots 9 qui sont sensiblement coaxiaux et qui font saillie à l'opposé l'un de l'autre et dans une direction transversale aux bras de fourche 7. Les deux ergots 9 sont reçus dans des logements respectifs prévus sur la semelle 3, et forment en partie la liaison pivot avant P1.According to the embodiment shown in the figures, the free ends of the two fork arms 7 respectively comprise two lugs 9 which are substantially coaxial and which project opposite each other and in a direction transverse to the arms fork 7. The two lugs 9 are received in respective housings provided on the sole 3, and partly form the front pivot connection P1.

Le suceur d'aspirateur 2 comprend également deux roues principales 11, également nommées roues arrière, destinées à rouler sur une surface à nettoyer. Les deux roues principales 11 sont montées mobiles en rotation sur la fourche 6 autour d'un axe de roue A qui est parallèle à l'axe de pivotement avant X1, et qui est donc également sensiblement horizontal lorsque le suceur d'aspirateur 2 repose sur une surface horizontale. De façon avantageuse, les roues principales 11 sont disposées de part et d'autre de la fourche 6, et plus particulièrement de part et d'autre de la partie de liaison 8.The vacuum cleaner nozzle 2 also includes two main wheels 11, also called rear wheels, intended to roll on a surface to be cleaned. The two main wheels 11 are mounted to rotate on the fork 6 around a wheel axis A which is parallel to the front pivot axis X1, and which is therefore also substantially horizontal when the vacuum cleaner nozzle 2 rests on a horizontal surface. Advantageously, the main wheels 11 are arranged on either side of the fork 6, and more particularly on either side of the connecting part 8.

Le suceur d'aspirateur 2 comprend de plus un manchon de raccordement 12 à l'extrémité duquel vient se raccorder un embout d'un tube d'aspiration (non illustré) lui-même raccordé au système d'aspiration d'un aspirateur (non illustré). Diverses variantes d'aspirateurs existent déjà sur le marché et pourront être utilisées avec le suceur d'aspirateur 2 selon l'invention ; ces variantes étant connues de l'homme du métier, elles ne sont pas détaillées dans le présent document.The vacuum cleaner nozzle 2 further comprises a connection sleeve 12 at the end of which is connected a tip of a suction tube (not illustrated) itself connected to the suction system of a vacuum cleaner (not illustrated). Various variants of vacuum cleaners already exist on the market and can be used with the vacuum cleaner nozzle 2 according to the invention; these variants being known to those skilled in the art, they are not detailed in this document.

Le suceur d'aspirateur 2 comprend également un conduit de liaison flexible 13 (voir la figure 4) reliant fluidiquement la cavité d'aspiration 5 au manchon de raccordement 12.The vacuum cleaner nozzle 2 also includes a flexible connecting conduit 13 (see the figure 4 ) fluidly connecting the suction cavity 5 to the connection sleeve 12.

Le suceur d'aspirateur 2 comporte en outre un organe de liaison 14 reliant mécaniquement le manchon de raccordement 12 à la fourche 6. De façon avantageuse, la partie de liaison 8 de la fourche 6 s'étend en dessous de l'organe de liaison 14, et les roues principales 11 sont disposées de part et d'autre de l'organe de liaison 14.The vacuum cleaner nozzle 2 further comprises a connecting member 14 mechanically connecting the connecting sleeve 12 to the fork 6. Advantageously, the connecting part 8 of the fork 6 extends below the connecting member 14, and the main wheels 11 are arranged on either side of the connecting member 14.

Le manchon de raccordement 12 est plus particulièrement monté articulé sur l'organe de liaison 14 par l'intermédiaire d'une liaison pivot arrière P2 définissant un axe de pivotement arrière X2 qui est parallèle à l'axe de pivotement avant X1. Ainsi, le manchon de raccordement 12 peut basculer vers l'arrière ou vers l'avant par rapport à l'organe de liaison 14, comme l'illustrent respectivement les flèches F3 et F4 sur la figure 6.The connection sleeve 12 is more particularly mounted articulated on the connecting member 14 via a rear pivot connection P2 defining a rear pivot axis X2 which is parallel to the front pivot axis X1. Thus, the connection sleeve 12 can tilt backwards or forwards relative to the connecting member 14, as illustrated respectively by arrows F3 and F4 on the Figure 6 .

Selon le mode de réalisation représenté sur les figures, lorsque les deux roues principales 11 du suceur d'aspirateur 2 reposent sur une surface horizontale, la distance entre l'axe de pivotement arrière X2 et la surface horizontale est supérieure à la distance entre l'axe de roue A et la surface horizontale. Selon le mode de réalisation représenté sur les figures, l'axe de pivotement arrière X2 est légèrement décalé vers l'arrière vis-à-vis de l'axe de roue A. Toutefois, selon une variante de réalisation de l'invention, l'axe de pivotement arrière X2 pourrait correspondre à l'axe de roue A ou être légèrement décalé vers l'avant vis-à-vis de l'axe de roue A. Une telle disposition de l'axe de pivotement arrière X2 permet d'éviter un basculement du suceur lorsqu'un utilisateur exerce une force d'appui sur le tube d'aspiration raccordé au manchon de raccordement 12.According to the embodiment shown in the figures, when the two main wheels 11 of the vacuum cleaner nozzle 2 rest on a horizontal surface, the distance between the rear pivot axis X2 and the horizontal surface is greater than the distance between the wheel axle A and the horizontal surface. According to the embodiment shown in the figures, the rear pivot axis X2 is slightly offset rearward with respect to the wheel axis A. However, according to a variant embodiment of the invention, the 'axis of rear pivot X2 could correspond to wheel axis A or be slightly offset towards the front with respect to wheel axis A. Such an arrangement of the rear pivot axis of the nozzle when a user exerts a pressing force on the suction tube connected to the connection sleeve 12.

L'organe de liaison 14 est monté articulé sur la fourche 6 par l'intermédiaire d'une liaison pivot centrale P3 définissant un axe de rotation X3 qui s'étend perpendiculairement à l'axe de pivotement avant X1. La liaison pivot centrale P3 est située entre la liaison pivot arrière P2 et la liaison pivot avant P1, et plus particulièrement entre la liaison pivot avant P1 et l'axe de roue A. De façon avantageuse, la liaison pivot centrale P3 est disposée entre les deux bras de fourche 7.The connecting member 14 is mounted articulated on the fork 6 via a central pivot connection P3 defining an axis of rotation X3 which extends perpendicular to the front pivot axis X1. The central pivot connection P3 is located between the rear pivot connection P2 and the front pivot connection P1, and more particularly between the front pivot connection P1 and the wheel axle A. Advantageously, the central pivot connection P3 is arranged between the two fork arms 7.

Comme montré plus particulièrement sur la figure 6, lorsque les deux roues principales 11 du suceur d'aspirateur 2 reposent sur une surface horizontale, l'axe de rotation X3 est sensiblement horizontal ou est incliné par rapport à la surface horizontale d'un angle d'inclinaison inférieur à 10°, et par exemple inférieure à 5°.As shown more particularly on the Figure 6 , when the two main wheels 11 of the vacuum cleaner nozzle 2 rest on a horizontal surface, the axis of rotation X3 is substantially horizontal or is inclined relative to the horizontal surface by an angle of inclination less than 10°, and for example less than 5°.

Comme montré également sur la figure 6, l'axe de roue A est sécant avec l'organe de liaison 14, et un plan passant par l'axe de pivotement avant X1 et par l'axe de roue A est également sécant avec l'organe de liaison 14. De façon avantageuse, l'axe de rotation X3 est situé dans un plan longitudinal vertical médian du suceur d'aspirateur 2. L'axe de rotation X3 peut être situé légèrement au-dessus ou en dessous d'un plan passant par l'axe de pivotement avant X1 et par l'axe de roue A.As also shown on the Figure 6 , the wheel axle A intersects with the connecting member 14, and a plane passing through the front pivot axis X1 and through the wheel axle A is also intersecting with the connecting member 14. advantageously, the axis of rotation X3 is located in a median vertical longitudinal plane of the vacuum cleaner nozzle 2. The axis of rotation X3 can be located slightly above or below a plane passing through the pivot axis front X1 and through wheel axle A.

Selon le mode de réalisation représenté sur les figures, l'organe de liaison 14 comporte une partie de montage 14.1 qui est annulaire et qui est montée mobile en rotation sur la fourche 6 autour de l'axe de rotation X3, et en outre une partie de support 14.2 sur laquelle est monté articulé le manchon de raccordement 12.According to the embodiment shown in the figures, the connecting member 14 comprises a mounting part 14.1 which is annular and which is mounted movable in rotation on the fork 6 around the axis of rotation X3, and in addition a part support 14.2 on which the connection sleeve 12 is hingedly mounted.

L'organe de liaison 14 délimite un passage 15 dans lequel s'étend le conduit de liaison flexible 13. De façon avantageuse, la partie de montage 14.1 s'étend autour du conduit de liaison flexible 13, et la partie de support 14.2 présente une section transversale globalement en U et s'étend en dessous du conduit de liaison flexible 13.The connecting member 14 delimits a passage 15 in which the flexible connecting conduit 13 extends. Advantageously, the mounting part 14.1 extends around the flexible connecting conduit 13, and the support part 14.2 has a generally U-shaped cross section and extends below the flexible connecting conduit 13.

Le suceur d'aspirateur 2 comprend de plus un organe de guidage 16 qui s'étend transversalement aux bras de fourche 7 et au-dessus de la partie de montage 14.1. L'organe de guidage 16 comporte une partie de guidage qui est arquée, et deux portions d'extrémité qui sont disposées de part et d'autre de l'organe de liaison 14 et qui sont fixées chacune à la fourche 6. La fourche 6 et l'organe de guidage 16 sont configurés pour guider en rotation l'organe de liaison 14 autour de l'axe de rotation X3, et forment ainsi en partie la liaison pivot centrale P3.The vacuum cleaner nozzle 2 further comprises a guide member 16 which extends transversely to the fork arms 7 and above the mounting part 14.1. The guide member 16 comprises a guide part which is arcuate, and two end portions which are arranged on either side of the connecting member 14 and which are each fixed to the fork 6. The fork 6 and the guide member 16 are configured to guide the connecting member 14 in rotation around the axis of rotation X3, and thus partly form the central pivot connection P3.
