La surface à aspirer peut par exemple être du carrelage, du parquet, du stratifié, de la moquette ou un tapis.Vacuum cleaners equipped with a vacuum cleaner nozzle are well known on the market, these making it possible to clean surfaces by suction for the evacuation of dust and waste of small particle size resting thereon. The surface to be vacuumed can for example be tiles, parquet, laminate, carpet or carpet.

Le document FR3062562 décrit un suceur d'aspirateur comprenant une semelle munie d'une face inférieure et d'une cavité d'aspiration débouchant sur la face inférieure, au moins une brosse, un manchon de raccordement configuré pour communiquer fluidiquement avec la cavité d'aspiration, et une fourche qui est agencée entre la semelle et le manchon de raccordement et qui est montée en liaisons pivots d'axes de pivotement transversaux vis-à-vis de la semelle et du manchon de raccordement, ledit suceur d'aspirateur comprenant un mécanisme d'actionnement de brosse comprenant une manette configurée pour occuper au moins une première position de manette, une deuxième position de manette et une troisième position de manette, le mécanisme d'actionnement de brosse étant configuré pour :

  • lorsque la manette est déplacée dans la première position de manette, autoriser le pivotement de la fourche par rapport à la semelle et positionner l'au moins une brosse dans une position abaissée dans laquelle l'au moins une brosse est en saillie de la face inférieure,
  • lorsque la manette est déplacée dans la deuxième position de manette, autoriser le pivotement de la fourche par rapport à la semelle et positionner l'au moins une brosse dans une position relevée dans laquelle l'au moins une brosse est en retrait de la face inférieure,
  • lorsque la manette est déplacée dans la troisième position de manette, bloquer le pivotement de la fourche par rapport à la semelle et maintenir l'au moins une brosse dans la position relevée,
ledit mécanisme d'actionnement de brosse comprenant également un système d'indexation de manette configuré pour maintenir la manette dans au moins la première, la deuxième et la troisième positions de manette.The document FR3062562 describes a vacuum cleaner nozzle comprising a sole provided with a lower face and a suction cavity opening onto the lower face, at least one brush, a connecting sleeve configured to communicate fluidly with the suction cavity, and a fork which is arranged between the sole and the connection sleeve and which is mounted in pivot connections of transverse pivot axes with respect to the sole and the connection sleeve, said vacuum cleaner nozzle comprising a mechanism for A brush actuation comprising a joystick configured to occupy at least a first joystick position, a second joystick position and a third joystick position, the brush actuation mechanism being configured to:
  • when the joystick is moved into the first joystick position, allowing the fork to pivot relative to the sole and positioning the at least one brush in a lowered position in which the at least one brush projects from the underside ,
  • when the joystick is moved to the second joystick position, allow the fork to pivot relative to the sole and position the at least one brush in a raised position in which the at least one brush is set back from the underside,
  • when the lever is moved into the third lever position, blocking the pivoting of the fork relative to the sole and maintaining the at least one brush in the raised position,
said brush actuation mechanism also comprising a joystick indexing system configured to hold the joystick in at least the first, second and third joystick positions.

Un tel suceur d'aspirateur est configuré de telle sorte que, lorsque le pivotement de la fourche vis-à-vis de la semelle est bloqué, la semelle occupe une position prédéterminée qui procure au suceur d'aspirateur des performances d'aspiration et de grattage optimales notamment pour l'aspiration de certains sols mous.Such a vacuum cleaner nozzle is configured in such a way that, when the pivoting of the fork with respect to the sole is blocked, the sole occupies a predetermined position which provides the vacuum cleaner nozzle with suction performance and particularly for vacuuming certain soft floors.

Afin d'éviter un déplacement indésirable de la manette notamment de la troisième position de manette vers la deuxième position de manette lors de l'utilisation du suceur d'aspirateur (un tel déplacement pourrait être induit par les efforts importants appliqués sur le suceur d'aspirateur lors de son utilisation) et donc une modification préjudiciable de la position de la semelle par rapport au sol à aspirer, le système d'indexation de manette est plus particulièrement configuré de telle sorte que des efforts relativement importants doivent être appliqués par l'utilisateur sur la manette pour permettre un déplacement de cette dernière de la troisième position de manette vers la deuxième position de manette.In order to avoid undesirable movement of the lever, in particular from the third position of the lever to the second position of the lever when using the vacuum cleaner nozzle (such a movement could be induced by the significant forces applied to the nozzle of vacuum cleaner during its use) and therefore a detrimental modification of the position of the sole with respect to the ground to be vacuumed, the lever indexing system is more particularly configured in such a way that relatively large forces must be applied by the user on the joystick to allow movement of the latter from the third joystick position to the second joystick position.

Toutefois, la nécessité d'appliquer des efforts relativement importants sur la manette pour permettre son déplacement entre ses différentes positions peut s'avérer désagréable pour certains utilisateurs, voire rendre difficile l'utilisation du suceur d'aspirateur pour certains utilisateurs.However, the need to apply relatively large forces to the lever to allow it to move between its different positions can prove to be unpleasant for some users, or even make it difficult to use the vacuum cleaner nozzle for some users.

De plus, une telle configuration du système d'indexation de manette peut induire des ruptures de certaines pièces en matière plastique constitutives du système d'indexation de manette.In addition, such a configuration of the lever indexing system can lead to breakage of certain constituent plastic parts of the lever indexing system.

A cet effet, la présente invention concerne un suceur d'aspirateur comprenant une semelle munie d'une face inférieure et d'une cavité d'aspiration débouchant sur la face inférieure, au moins une brosse, un manchon de raccordement configuré pour communiquer fluidiquement avec la cavité d'aspiration, et une fourche qui est agencée entre la semelle et le manchon de raccordement et qui est montée en liaisons pivots d'axes de pivotement transversaux vis-à-vis de la semelle et du manchon de raccordement, ledit suceur d'aspirateur comprenant un mécanisme d'actionnement de brosse comprenant une manette configurée pour occuper au moins une première position de manette, une deuxième position de manette et une troisième position de manette, le mécanisme d'actionnement de brosse étant configuré pour :

  • lorsque la manette est déplacée dans la première position de manette, autoriser le pivotement de la fourche par rapport à la semelle et positionner l'au moins une brosse dans une position abaissée dans laquelle l'au moins une brosse est en saillie de la face inférieure,
  • lorsque la manette est déplacée dans la deuxième position de manette, autoriser le pivotement de la fourche par rapport à la semelle et positionner l'au moins une brosse dans une position relevée dans laquelle l'au moins une brosse est en retrait de la face inférieure,
  • lorsque la manette est déplacée dans la troisième position de manette, bloquer le pivotement de la fourche par rapport à la semelle et maintenir l'au moins une brosse dans la position relevée,
ledit mécanisme d'actionnement de brosse comprenant également un système d'indexation de manette configuré pour maintenir la manette dans au moins la première, la deuxième et la troisième positions de manette, caractérisé en ce que le mécanisme d'actionnement de brosse comprend, en plus du système d'indexation de manette, un dispositif de verrouillage comprenant un verrou mobile entre une première position de verrou dans laquelle le verrou bloque le pivotement de la fourche vis-à-vis de la semelle et une deuxième position de verrou dans laquelle le verrou autorise le pivotement de la fourche par rapport à la semelle.To this end, the present invention relates to a vacuum cleaner nozzle comprising a sole provided with a lower face and a suction cavity opening onto the lower face, at least one brush, a connection sleeve configured to communicate fluidly with the suction cavity, and a fork which is arranged between the soleplate and the connection sleeve and which is mounted in pivot connections with transverse pivot axes with respect to the soleplate and the connection sleeve, said nozzle d vacuum cleaner comprising a brush actuation mechanism comprising a joystick configured to occupy at least a first joystick position, a second joystick position and a third joystick position, the brush actuation mechanism being configured to:
  • when the joystick is moved into the first joystick position, allowing the fork to pivot relative to the sole and positioning the at least one brush in a lowered position in which the at least one brush projects from the underside ,
  • when the lever is moved into the second lever position, allowing the fork to pivot relative to the sole and positioning the at least one brush in a raised position in which the at least one brush is set back from the underside ,
  • when the lever is moved into the third lever position, blocking the pivoting of the fork relative to the sole and maintaining the at least one brush in the raised position,

Une telle configuration du mécanisme d'actionnement de brosse permet de dissocier l'indexation de la manette du verrouillage du pivotement de la fourche par rapport à la semelle. Ces dispositions permettent en particulier d'une part de nécessiter moins d'efforts pour assurer un maintien de la manette dans une position sélectionnée par l'utilisateur et donc de faciliter son déplacement par ce dernier, et d'autre part d'assurer un meilleur verrouillage du pivotement de la fourche par rapport à la semelle lorsque la manette est dans la troisième position de manette.Such a configuration of the brush actuation mechanism makes it possible to dissociate the indexing of the handle from the locking of the pivoting of the fork with respect to the sole.

Le mécanisme d'actionnement de brosse 14 comprend également, en plus du système d'indexation de manette 16, un dispositif de verrouillage 26 configuré pour verrouiller les brosses 13.1, 13.2, 13.3 dans la position abaissée.The brush actuation mechanism 14 also includes, in addition to the handle indexing system 16, a locking device 26 configured to lock the brushes 13.1, 13.2, 13.3 in the lowered position.

Le dispositif de verrouillage 26 comprend une pluralité d'organes de verrouillage 27 qui sont chacun disposés à la verticale d'une brosse respective et qui sont chacun configurés pour empêcher un déplacement de la brosse respective de la position abaissée vers la position relevée. Selon le mode de réalisation représenté sur les figures, le dispositif de verrouillage 26 comprend une première paire d'organes de verrouillage 27 disposés à la verticale respectivement des brosses 13.1, 13.2, et une deuxième paire d'organes de verrouillage 27 disposés à la verticale de la brosse 13.3.The locking device 26 comprises a plurality of locking members 27 which are each arranged vertically to a respective brush and which are each configured to prevent a movement of the respective brush from the lowered position to the raised position. According to the embodiment shown in the figures, the locking device 26 comprises a first pair of locking members 27 arranged vertically respectively brushes 13.1, 13.2, and a second pair of locking members 27 arranged vertically of the brush 13.3.

Selon le mode de réalisation représenté sur les figures, chaque organe de verrouillage 27 est formé par un basculeur qui est mobile en rotation sur la semelle 6 autour d'un axe de rotation A et entre une position de verrouillage (voir les figures 5 à 7) dans laquelle le basculeur empêche un déplacement de la brosse respective de la position abaissée vers la position relevée, et une position de libération (voir les figures 9 à 14) dans laquelle le basculeur autorise un déplacement de la brosse respective de la position abaissée vers la position relevée. Avantageusement, l'axe de rotation A de chaque basculeur s'étend sensiblement transversalement à l'axe de pivotement de la manette 15.According to the embodiment shown in the figures, each locking member 27 is formed by a rocker which is rotatable on the sole 6 around an axis of rotation A and between a locking position (see the figures 5 to 7 ) in which the rocker prevents movement of the respective brush from the lowered position to the raised position, and a release position (see the figures 9 to 14 ) wherein the rocker allows movement of the respective brush from the lowered position to the raised position. Advantageously, the axis of rotation A of each rocker extends substantially transversely to the pivot axis of the handle 15.

Chaque loquet de verrouillage comprend une portion de butée 46 comportant une surface inférieure de butée 46.1. Dans la troisième position de manette (figures 12 et 13), les loquets de verrouillage sont dans la première position de verrou où chaque portion de butée 46 s'étend au-dessus d'un doigt d'appui respectif 34, 35. Dans cette première position de verrou, chaque surface inférieure de butée 46.1 vient par exemple en butée contre une surface supérieure d'appui 34.1 et 35.1 appartenant à chacun des doigts d'appuis 34, 35 pour empêcher tout pivotement de la fourche 4 par rapport à la semelle 6.As depicted in figure 5 , 9 , 12 and 13 , each latch 36 may be in the form of a locking latch mounted so as to be able to rotate on the sole 6 around the axis of rotation B. Each locking latch comprises an abutment portion 46 comprising a lower abutment surface 46.1. In the third lever position ( figures 12 and 13 ), the locking latches are in the first locking position where each abutment portion 46 extends above a respective bearing finger 34, 35. In this first locking position, each lower surface of the abutment 46.1 abuts for example against an upper bearing surface 34.1 and 35.1 belonging to each of the bearing fingers 34, 35 to prevent any pivoting of the fork 4 relative to the sole 6.

Comme montré sur les figures 12 à 14, chaque coulisseau 23 est configuré pour occuper une troisième position de coulisseau dans laquelle les brosses 13.1, 13.2, 13.3 sont dans la position relevée, et le mécanisme d'actionnement de brosse 14 est configuré de telle sorte qu'un déplacement de la manette 15 de la deuxième position de manette à la troisième position de manette entraîne un déplacement de chaque coulisseau 23 de la deuxième position de coulisseau à la troisième position de coulisseau, et de telle sorte qu'un déplacement de la manette 15 de la troisième position de manette à la deuxième position de manette entraîne un déplacement de chaque coulisseau 23 de la troisième position de coulisseau à la deuxième position de coulisseau.As shown on the figures 12 to 14 , each slider 23 is configured to occupy a third slider position in which the brushes 13.1, 13.2, 13.3 are in the raised position, and the brush actuation mechanism 14 is configured such that movement of the handle 15 from the second lever position to the third lever position causes a movement of each slider 23 from the second slider position to the third slider position, and such that a movement of the lever 15 from the third lever position at the second lever position causes each slider 23 to move from the third slider position to the second slider position.

Chaque coulisseau 23 est plus particulièrement configuré pour déplacer un verrou 36 respectif de la première position de verrou à la deuxième position de verrou lorsque ledit coulisseau 23 est déplacé de la troisième position de coulisseau à la deuxième position de coulisseau, et pour autoriser un déplacement du verrou 36 respectif de la deuxième position de verrou à la première position de verrou lorsque ledit coulisseau 23 est déplacé de la deuxième position de coulisseau à la troisième position de coulisseau. A cet effet, chaque coulisseau 23 peut avantageusement comprendre une surface inclinée 37, également nommée rampe, configurée pour coopérer avec le verrou 36 respectif lorsque ledit coulisseau 23 est déplacé de la troisième position de coulisseau à la deuxième position de coulisseau. Lorsque ledit coulisseau 23 est déplacé de la troisième position de coulisseau à la deuxième position de coulisseau, la surface inclinée vient repousser en rotation chaque verrou, par exemple chaque loquet, contre les forces de rappel exercées par les moyens de rappel précités. Ce déplacement des coulisseaux a pour effet d'entrainer en rotation chaque loquet vers la deuxième position de verrou où chaque portion de butée 46 est rétractée par rapport à chaque surface supérieure d'appui 34.1, 35.1. Dans leur position rétractée, les portions de butée 46 ne sont plus au-dessus des doigts d'appuis 34, 35. Dans cette position rétractée des portions de butée 46, le pivotement de la fourche 4 par rapport à la semelle 6 est autorisé.Each slider 23 is more particularly configured to move a respective lock 36 from the first lock position to the second lock position when said slider 23 is moved from the third slider position to the second slider position, and to allow movement of the respective latch 36 from the second latch position to the first latch position when said slider 23 is moved from the second slider position to the third slider position. To this end, each slider 23 can advantageously comprise an inclined surface 37, also called a ramp, configured to cooperate with the respective lock 36 when said slider 23 is moved from the third slider position to the second slider position. When said slider 23 is moved from the third slider position to the second slider position, the inclined surface pushes in rotation each lock, for example each latch, against the restoring forces exerted by the means of aforementioned reminder. This movement of the sliders has the effect of rotating each latch towards the second lock position where each stop portion 46 is retracted with respect to each upper bearing surface 34.1, 35.1. In their retracted position, the stop portions 46 are no longer above the support fingers 34, 35. In this retracted position of the stop portions 46, the pivoting of the fork 4 with respect to the sole 6 is authorized.

De façon avantageuse, chaque coulisseau 23 est également configuré pour maintenir le verrou 36 respectif dans la deuxième position de verrou lorsque ledit coulisseau 23 est déplacé entre la première position de coulisseau et la deuxième position de coulisseau.Advantageously, each slider 23 is also configured to maintain the respective lock 36 in the second lock position when said slider 23 is moved between the first slider position and the second slider position.

Un fonctionnement du suceur d'aspirateur 2 selon la présente invention va maintenant être décrit en référence plus particulièrement aux figures 6 à 14.An operation of the vacuum cleaner nozzle 2 according to the present invention will now be described with more particular reference to the figures 6 to 14 .

Lorsque la manette 15 est déplacée dans la troisième position de manette, les organes de butée supérieurs 32 viennent en appui respectivement contre les premier et deuxième doigts d'appui 34, 35 de la fourche 4 et déplacent les premier et deuxième doigts d'appui 34, 35 jusqu'à ce que ces derniers viennent en contact contre les organes de butée inférieurs prévus sur la semelle 6.When the lever 15 is moved into the third lever position, the upper abutment members 32 come to bear respectively against the first and second support fingers 34, 35 of the fork 4 and move the first and second support fingers 34 , 35 until the latter come into contact against the lower abutment members provided on the sole 6.

Un tel déplacement de la manette 15 dans la troisième position de manette induit également un déplacement des coulisseaux 23 dans la troisième position de coulisseau, du fait de la coopération des parties crantées 24 avec les crémaillères 25, et donc un déplacement des verrous 36, sous l'action des moyens de rappel respectifs, dans la première position de verrou dans laquelle les verrous 36 bloquent les première et deuxièmes branches 4.1, 4.2 de la fourche 4 et empêchent donc tout pivotement de la fourche 4 par rapport à la semelle 6. Il convient d'être rappelé que les brosses 13.1, 13.2, 13.3 sont maintenues dans la position relevée lorsque la manette 15 est dans la troisième position de manette.Such a movement of the lever 15 into the third lever position also induces a movement of the sliders 23 into the third slider position, due to the cooperation of the toothed parts 24 with the racks 25, and therefore a movement of the locks 36, under the action of the respective return means, in the first lock position in which the locks 36 block the first and second branches 4.1, 4.2 of the fork 4 and therefore prevent any pivoting of the fork 4 relative to the sole 6. It should be recalled that the brushes 13.1, 13.2, 13.3 are held in the raised position when the handle 15 is in the third handle position.

Lorsque la manette 15 est déplacée dans la deuxième position de manette, les organes de butée supérieurs 32 s'éloignent des organes de butée inférieurs et libèrent donc les premier et deuxième doigts d'appui 34, 35 de la fourche 4.When the handle 15 is moved into the second handle position, the upper stop members 32 move away from the lower stop members and therefore release the first and second support fingers 34, 35 of the fork 4.

Un tel déplacement de la manette 15 dans la deuxième position de manette induit également un déplacement des coulisseaux 23 dans la deuxième position de coulisseau, du fait de la coopération des parties crantées 24 avec les crémaillères 25, et donc un déplacement des verrous 36, sous l'action des surfaces inclinées 37 prévues sur les coulisseaux 23, dans la deuxième position de verrou, de manière à autoriser un pivotement de la fourche 4 par rapport à la semelle 6. Lorsque les coulisseaux 23 sont dans la deuxième position de coulisseau, les verrous 36 sont maintenus dans la deuxième position de verrou par les coulisseaux 23.Such a movement of the lever 15 into the second lever position also induces a movement of the sliders 23 into the second slider position, due to the cooperation of the toothed parts 24 with the racks 25, and therefore a movement of the locks 36, under the action of the inclined surfaces 37 provided on the sliders 23, in the second lock position, so as to allow the fork 4 to pivot relative to the sole 6. When the sliders 23 are in the second slider position, the locks 36 are held in the second lock position by sliders 23.

Lorsque la manette 15 est déplacée dans la première position de manette, les organes de butée supérieurs 32 s'éloignent encore des organes de butée inférieurs de manière à augmenter encore la course de pivotement de la fourche 4 par rapport à la semelle 6.When the lever 15 is moved into the first lever position, the upper abutment members 32 move further away from the lower abutment members so as to further increase the pivoting travel of the fork 4 relative to the sole 6.

Un tel déplacement de la manette 15 dans la première position de manette induit également un déplacement des coulisseaux 23 dans la première position de coulisseau, et donc une coopération des galets de roulement 28 prévus sur les coulisseaux 23 avec les surfaces de roulement 29 prévues sur les basculeurs respectifs, de manière à déplacer chaque basculeur de sa position de libération à sa position de verrouillage. Un tel déplacement de chaque basculeur induit alors un coulissement des supports de brosse 12.1, 12.2, 12.3 dans leur première position de support, et donc un déplacement des brosses 13.1, 13.2, 13.3 dans leur position abaissée dans laquelle les brosses 13.1, 13.2, 13.3 font saillie de la face inférieure de la semelle 6.Such a movement of the lever 15 into the first lever position also induces a movement of the sliders 23 into the first slider position, and therefore a cooperation of the rollers 28 provided on the sliders 23 with the rolling surfaces 29 provided on the respective rockers, so as to move each rocker from its release position to its locking position. Such a displacement of each rocker then induces a sliding of the brush supports 12.1, 12.2, 12.3 in their first support position, and therefore a displacement of the brushes 13.1, 13.2, 13.3 in their lowered position in which the brushes 13.1, 13.2, 13.3 protrude from the underside of the sole 6.

Ainsi, le mécanisme d'actionnement de brosse 14 permet d'indexer la manette 15 dans une première position de manette, une deuxième position de manette et une troisième position de manette correspondant respectivement à un premier mode de fonctionnement, dit « mode de performances maximales », dans lequel les brosses 13.1, 13.2, 13.3 sont dans la position relevée et le pivotement de la fourche 4 par rapport à la semelle 6 est bloqué, un deuxième mode de fonctionnement, dit « mode confort », dans lequel les brosses 13.1, 13.2, 13.3 sont dans la position relevée et le pivotement de la fourche 4 par rapport à la semelle 6 est autorisé, et un troisième mode de fonctionnement, dit « mode sol dur », dans lequel les brosses 13.1, 13.2, 13.3 sont dans la position abaissée et le pivotement de la fourche 4 par rapport à la semelle 6 est autorisé.Thus, the brush actuation mechanism 14 makes it possible to index the handle 15 in a first handle position, a second handle position and a third handle position corresponding respectively to a first mode of operation, called "maximum performance mode". ", in which the brushes 13.1, 13.2, 13.3 are in the raised position and the pivoting of the fork 4 relative to the sole 6 is blocked, a second operating mode, called "comfort mode", in which the brushes 13.1, 13.2, 13.3 are in the raised position and the pivoting of the fork 4 relative to the sole 6 is authorized, and a third mode of operation, called "hard ground mode", in which the brushes 13.1, 13.2, 13.3 are in the lowered position and the pivoting of the fork 4 relative to the sole 6 is authorized.

Bien entendu, la présente invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the present invention is in no way limited to the embodiment described and illustrated which has been given only by way of example. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
