Description détaillée de l'inventionDetailed description of the invention

Les figures 1 et 2 représentent une vue éclatée en perspective d'un robot aspirateur selon l'invention, comprenant un corps principal 10 à roulettes 12, et un aspirateur à main 20.The figures 1 and 2 show an exploded perspective view of a vacuum robot according to the invention, comprising a main body 10 with rollers 12, and a hand vacuum cleaner 20.

Sur ces figures 1 et 2, le corps principal 10 est une base mobile avec des roulettes 12, dont au moins une est motrice. Une paroi latérale 13 du corps principal 10 comprend notamment des pare-chocs 14, une paroi lisse 15 et un bord périphérique arrière 16.On these figures 1 and 2 , the main body 10 is a movable base with rollers 12, at least one of which is driving. A side wall 13 of the main body 10 comprises in particular bumpers 14, a smooth wall 15 and a rear peripheral edge 16.

L'aspirateur à main 20 comprend en particulier une poignée de préhension 21, un embout d'aspiration 22, une paroi arrière 24 visibles sur les figures 1 et 2, ainsi que des moyens d'aspiration autonomes non visibles sur les figures, c'est-à-dire un moto-ventilateur et des moyens de stockage d'énergie électrique, autrement dit une batterie.The hand-held vacuum cleaner 20 comprises in particular a gripping handle 21, a suction nozzle 22, a rear wall 24 visible on the figures 1 and 2 , as well as autonomous suction means not visible in the figures, that is to say a motor-fan and means for storing electrical energy, in other words a battery.

L'aspirateur à main 20 peut s'accoupler de manière réversible au corps principal 10 pour former le robot aspirateur. En effet, l'aspirateur à main 20 permet alors de procurer les moyens d'aspiration, et le corps principal procure la capacité de déplacement sur un sol à nettoyer.The hand-held vacuum cleaner 20 can reversibly couple to the main body 10 to form the vacuum robot. In fact, the hand-held vacuum cleaner 20 then makes it possible to provide the suction means, and the main body provides the capacity to move on a floor to be cleaned.

La figure 2 étant une vue arrière en perspective, cette figure 2 montre un logement 19 ménagé dans le corps principal 10, dans lequel peut être logé l'aspirateur à main 20. Plus particulièrement, une surface d'accostage 17 avec une portion arrière plane qui se termine en entonnoir est prévue pour permettre à l'utilisateur de poser l'aspirateur à main 20 dans le logement 19, et de pousser l'aspirateur à main 20 aisément en position accostée.The figure 2 being a rear perspective view, this figure 2 shows a housing 19 formed in the main body 10, in which the hand vacuum cleaner 20 can be housed. More particularly, a docking surface 17 with a flat rear portion which ends in a funnel is provided to allow the user to put the hand-held vacuum cleaner 20 in the housing 19, and to push the hand-held vacuum cleaner 20 easily into the docked position.

Comme cela sera expliqué plus en détail ci-après, le corps principal 10 comprend une protrusion 18 sur la surface d'accostage 17, pour permettre un engagement avec une contre-forme 23 de l'aspirateur à main 20, de sorte à permettre un verrouillage une fois l'aspirateur à main 20 accouplé au corps principal 10.As will be explained in more detail hereinafter, the main body 10 includes a protrusion 18 on the docking surface 17, to allow engagement with a counterframe 23 of the hand vacuum cleaner 20, so as to allow a locking once the hand-held vacuum cleaner 20 has been coupled to the main body 10.

La figure 3 montre en vue de dessus le robot aspirateur avec l'aspirateur à main 20 accouplé au corps principal 10. Cette figure montre en traits mixtes une surface latérale enveloppe 100 formée par la paroi latérale du robot aspirateur. Cette paroi latérale du robot aspirateur comprend notamment la paroi latérale 13 du corps principal et la paroi arrière 24 de l'aspirateur à main 20. La figure 3 montre à dessein pour la compréhension un espace entre la paroi latérale externe du robot aspirateur et la surface latérale enveloppe 100, mais sur cette vue de dessus, la paroi latérale externe du robot aspirateur et la surface latérale enveloppe sont confondues.The figure 3 shows a top view of the vacuum cleaner robot with the hand vacuum cleaner 20 coupled to the main body 10. This figure shows in phantom lines a side surface envelope 100 formed by the side wall of the vacuum cleaner robot. This side wall of the robot vacuum cleaner comprises in particular the side wall 13 of the main body and the rear wall 24 of the hand vacuum cleaner 20. The figure 3 purposely for the sake of understanding a space between the outer side wall of the vacuum robot and the shell side surface 100, but in this top view, the outer side wall of the robot vacuum and the shell side surface are merged.

Comme le montre bien la figure 3, la paroi latérale et donc la surface latérale enveloppe 100 du robot aspirateur sont de section circulaire, pour permettre une navigation et des virages ou demi tours aisés pour le robot aspirateur si ce dernier rencontre un obstacle (détecté notamment par les pare-chocs 14). En effet, une telle section circulaire, et donc une forme générale cylindrique, permet au robot aspirateur de tourner ou pivoter sans interférence avec un éventuel obstacle en appui ou très proche de la paroi latérale. En conséquence, la surface latérale enveloppe 100 présente une section circulaire.As the figure 3 , the side wall and therefore the side surface envelope 100 of the vacuum cleaner robot are of circular section, to allow navigation and easy turns or U-turns for the vacuum cleaner robot if the latter encounters an obstacle (detected in particular by the bumpers 14) . Indeed, such a circular section, and therefore a generally cylindrical shape, allows the vacuum cleaner robot to rotate or pivot without interference with any obstacle bearing or very close to the side wall. Consequently, the envelope side surface 100 has a circular section.

La figure 4 montre le robot aspirateur avec l'aspirateur à main 20 accouplé au corps principal 10, selon une vue en perspective, et la figure 5 montre la surface latérale enveloppe 100 construite à partir de la paroi latérale du robot aspirateur.The figure 4 shows the vacuum robot with the hand vacuum cleaner 20 coupled to the main body 10, in a perspective view, and the figure 5 shows the envelope side surface 100 constructed from the side wall of the vacuum robot.

Selon un aspect de la présente invention, la poignée de préhension 21 est mobile entre :

  • une position déployée (voir figures 1 et 2) pour permettre à un utilisateur de manipuler l'aspirateur à main 20,
  • une position escamotée, (voir figures 3 et 4), lorsque l'aspirateur à main 20 est accouplé sur le corps principal.
According to one aspect of the present invention, the gripping handle 21 is movable between:
  • a deployed position (see figures 1 and 2 ) to allow a user to handle the hand vacuum cleaner 20,
  • a retracted position, (see figures 3 and 4 ), when the hand vacuum cleaner 20 is coupled to the main body.

Selon l'exemple représenté, la poignée de préhension est mobile en rotation, selon un axe de rotation sensiblement perpendiculaire au sol à nettoyer, lorsque les roulettes 12 du corps principal reposent sur le sol.According to the example shown, the gripping handle is movable in rotation, along an axis of rotation substantially perpendicular to the floor to be cleaned, when the rollers 12 of the main body rest on the floor.

Un aspect important est de prévoir que lorsque la poignée de préhension 21 est en position escamotée, la poignée de préhension 21 est soit tangente à la surface latérale enveloppe 100, soit en retrait. En conséquence, la capacité de manœuvre du robot aspirateur n'est pas affectée (car en position escamotée, la poignée de préhension 21 n'est pas en saillie par rapport à la surface latérale enveloppe ou la paroi latérale), et l'ergonomie d'utilisation est bonne (avec la poignée de préhension 21 en position déployée facile à saisir).An important aspect is to provide that when the gripping handle 21 is in the retracted position, the gripping handle 21 is either tangent to the envelope side surface 100, or recessed. Consequently, the maneuverability of the robot vacuum is not affected (because in the retracted position, the gripping handle 21 does not project from the side surface of the casing or the side wall), and the ergonomics of use is good (with the grip handle 21 in the extended position easy to grip).

La figure 5 montre bien que la poignée de préhension 21, représentée en traits pointillée et en position escamotée, est entièrement contenue dans la surface latérale enveloppe 100, et n'en fait pas saillie. Ainsi le robot aspirateur peut librement tourner sur lui-même.The figure 5 clearly shows that the gripping handle 21, shown in dotted lines and in the retracted position, is entirely contained in the lateral envelope surface 100, and does not protrude therefrom. Thus the vacuum robot can freely turn on itself.

La figure 6 montre la poignée de préhension 21 en position déployée, avec l'aspirateur à main 20 engagé dans le logement 19 du corps principal 10. Cette figure 6 montre donc soit la fin de l'accouplement, et il ne reste qu'à faire pivoter la poignée de préhension 21 vers la position escamotée, soit le début du désaccouplement, et il reste à tirer vers l'arrière l'aspirateur à main 20 pour le dégager complétement du corps principal 10. On peut prévoir un verrouillage de la poignée de préhension 21 en position déployée sur l'aspirateur à main 20, avec une première protrusion engagée dans une première contre-forme (non représentées).The figure 6 shows the grip handle 21 in the deployed position, with the hand vacuum cleaner 20 engaged in the housing 19 of the main body 10. This figure 6 therefore shows either the end of the coupling, and it only remains to rotate the gripping handle 21 towards the retracted position, or the beginning of the uncoupling, and it remains to pull back the hand vacuum cleaner 20 to completely disengage it from the main body 10. It is possible to provide a locking of the gripping handle 21 in the deployed position on the hand vacuum cleaner 20, with a first protrusion engaged in a first counter-form (not shown).

Lors d'une opération d'accouplement de l'aspirateur à main 20 sur le corps principal 10, il est également prévu de verrouiller l'aspirateur à main 20 sur le corps principal 10, pour sécuriser l'utilisation du robot aspirateur.During a coupling operation of the hand-held vacuum cleaner 20 on the main body 10, it is also provided to lock the hand-held vacuum cleaner 20 on the main body 10, to secure the use of the vacuum cleaner robot.

A cet effet, la protrusion 18 visible figure 2 est agencée pour s'engager dans la contre-forme 23 ménagée dans la poignée de préhension 21 lors de l'engagement de l'aspirateur à main 20 dans le logement 19 du corps principal 10. En fin de mouvement d'engagement, la protrusion 18 (qui comprend par exemple un épaulement) est complétement engagée dans la contre-forme 23 (qui peut être une rainure en Té).For this purpose, the visible protrusion 18 figure 2 is arranged to engage in the counter-form 23 formed in the gripping handle 21 during the engagement of the hand vacuum cleaner 20 in the housing 19 of the main body 10. At the end of the engagement movement, the protrusion 18 (which for example comprises a shoulder) is completely engaged in the counter-form 23 (which may be a T-shaped groove).

Lors de la rotation de la poignée de préhension 21 depuis sa position déployée (figures 1 et 2) vers sa position escamotée (figures 3 et 4), la rotation de la poignée de préhension 21 provoque le verrouillage de la poignée de préhension sur la protrusion 18, qui est emprisonnée dans la contre-forme 23. En conséquence, ce verrouillage provoque simultanément le verrouillage de l'aspirateur à main 20 sur le corps principal 10. En fin de rotation de la poignée de préhension, on peut prévoir un maintien en position escamotée avec un poussoir à bille qui s'engage dans une forme en creux par exemple.When rotating the gripping handle 21 from its deployed position ( figures 1 and 2 ) to its retracted position ( figures 3 and 4 ), the rotation of the gripping handle 21 causes the locking of the gripping handle on the protrusion 18, which is trapped in the counter-form 23. Consequently, this locking simultaneously causes the locking of the hand vacuum cleaner 20 on the main body 10. At the end of rotation of the gripping handle, it is possible to provide a maintenance in the retracted position with a ball pusher which engages in a hollow shape for example.

Lors du désaccouplement de l'aspirateur à main 20, l'utilisateur fait tout d'abord passer la poignée de préhension 21 de la position escamotée vers la position déployée, ce qui automatiquement dégage la protrusion 18 de la contre-forme 23, et l'utilisateur peut retirer l'aspirateur à main 20 du logement 19.When uncoupling the hand-held vacuum cleaner 20, the user first of all moves the gripping handle 21 from the retracted position to the deployed position, which automatically releases the protrusion 18 from the counter-form 23, and the The user can remove the hand vacuum cleaner 20 from the housing 19.

La figure 7 représente une mise en œuvre alternative d'un robot aspirateur selon l'invention.The figure 7 shows an alternative implementation of a vacuum robot according to the invention.

Selon cette mise en œuvre, l'aspirateur à main 20A comprend une poignée de préhension 21A qui est mobile en translation, et la paroi arrière 24A comprend un renfoncement. Cependant, selon cette mise en œuvre, la surface latérale enveloppe 100 est toujours un cylindre de section circulaire (car le corps principal 10A comprend un périmètre circulaire qui sert de base pour construire la surface latérale enveloppe 100), et en position escamotée, la poignée de préhension 21A est tangente ou en retrait de la surface latérale enveloppe.According to this implementation, the hand vacuum cleaner 20A comprises a gripping handle 21A which is movable in translation, and the rear wall 24A comprises a recess. However, according to this implementation, the envelope side surface 100 is still a cylinder of circular section (because the main body 10A includes a circular perimeter which serves as a base for constructing the envelope side surface 100), and in the retracted position, the handle grip 21A is tangent or set back from the envelope side surface.

Par ailleurs, selon cette mise en œuvre, le corps principal 10A comprend un logement 19A, une protrusion 18A, et une piste de came 18B sur une surface d'accostage 17A. En effet, comme on le voit figure 13, la poignée de préhension 21A, en position déployée, est verrouillée sur l'aspirateur à main 20A, par un pêne 221 (une première protrusion) engagé dans une gâche (une première contre-forme, non représentée) de l'aspirateur à main 20A. En début de mouvement d'accouplement de l'aspirateur à main 20A sur le corps principal 10A, une partie de commande du pêne 221 est repoussée vers le haut par la piste de came 18B, au travers d'une ouverture 23A du boîtier de l'aspirateur à main 20A, visible figure 9. En conséquence, le pêne 221 ne verrouille plus la poignée de préhension 21A sur l'aspirateur à main 20A, et la poignée de préhension 21A peut alors aller dans la position escamotée, poussée par l'utilisateur.Furthermore, according to this implementation, the main body 10A includes a housing 19A, a protrusion 18A, and a cam track 18B on a docking surface 17A. Indeed, as we see figure 13 , the gripping handle 21A, in the deployed position, is locked on the hand vacuum cleaner 20A, by a bolt 221 (a first protrusion) engaged in a keeper (a first counter-form, not shown) of the hand vacuum cleaner 20A. At the start of the coupling movement of the hand vacuum cleaner 20A on the main body 10A, an operating part of the bolt 221 is pushed upwards by the cam track 18B, through an opening 23A of the housing of the latch. 'hand-held vacuum cleaner 20A, visible figure 9 . Consequently, the bolt 221 no longer locks the gripping handle 21A on the hand vacuum cleaner 20A, and the gripping handle 21A can then go into the retracted position, pushed by the user.

La poignée de préhension 21A comprend également une gâchette 211, un renvoi 212, un index 214 (une deuxième protrusion) et un ressort 213 visibles figures 11 et 12, pour permettre un verrouillage de la poignée de préhension en position escamotée sur le corps principal 10, grâce à la protrusion 18A qui comprend un évidement interne (une deuxième contre-forme) comme le montre la figure 12.The gripping handle 21A also includes a trigger 211, a return 212, an index 214 (a second protrusion) and a spring 213 visible figures 11 and 12 , to allow locking of the gripping handle in the retracted position on the main body 10, thanks to the protrusion 18A which comprises an internal recess (a second counter-form) as shown in figure 12 .

Dans le détail, en fin d'accouplement de l'aspirateur à main 20A sur le corps principal 10A, une fois la poignée de préhension 21A déverrouillée de la position déployée, celle-ci se déplace horizontalement comme le montre la flèche PH de la figure 12. En fin de course, l'index 214 rencontre la protrusion 18A, et se soulève en raison de la poussée de l'utilisateur et de la présence d'un chanfrein, si bien qu'en toute fin de course de la poignée de préhension 21A, l'index 214 est en regard de l'évidement de la protrusion 18A, et y est poussé par l'action du ressort 213.In detail, at the end of the coupling of the hand vacuum cleaner 20A on the main body 10A, once the gripping handle 21A is unlocked from the deployed position, the latter moves horizontally as shown by the arrow PH of the figure 12 . At the end of the stroke, the index 214 meets the protrusion 18A, and rises due to the push of the user and the presence of a chamfer, so that at the very end of the stroke of the gripping handle 21A , the index 214 is opposite the recess of the protrusion 18A, and is pushed there by the action of the spring 213.

En conséquence, la poignée de préhension 21A est alors verrouillée sur le corps principal 10A, mais cela verrouille également l'aspirateur à main 20A sur le corps principal 10A. L'accouplement est alors sécurisé. En effet, seule une action de l'utilisateur sur la gâchette 211 peut soulever l'index 214 et déverrouiller la poignée de préhension 21A et l'aspirateur à main 20A du corps principal 10A.As a result, the grip handle 21A is then locked to the main body 10A, but this also locks the hand vacuum cleaner 20A to the main body 10A. The coupling is then secure. Indeed, only an action by the user on the trigger 211 can lift the index 214 and unlock the gripping handle 21A and the hand vacuum cleaner 20A of the main body 10A.

Par ailleurs, la protrusion 18A présente une section transversale en Té (visible figure 7), et s'engage dans une contre-forme 23B (une rainure en Té inversé) de l'aspirateur à main 20A, visible figure 9, de sorte à bloquer complétement l'aspirateur à main 20A sur le corps principal.Furthermore, the protrusion 18A has a T-shaped cross section (visible figure 7 ), and engages a counter-form 23B (an inverted T-slot) of the hand vacuum cleaner 20A, visible figure 9 , so as to completely block the hand vacuum cleaner 20A on the main body.

Enfin, on peut prévoir un ressort pour repousser automatiquement la poignée de préhension 21A depuis la position escamotée vers la position déployée, dès que la gâchette 211 est actionnée, toujours pour faciliter l'usage de l'appareil.Finally, a spring can be provided to automatically push the gripping handle 21A from the retracted position to the deployed position, as soon as the trigger 211 is actuated, again to facilitate the use of the device.

On comprendra que diverses modifications et/ou améliorations évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention décrits dans la présente description sans sortir du cadre de l'invention.It will be understood that various modifications and / or improvements obvious to a person skilled in the art can be made to the various embodiments of the invention described in the present description without departing from the scope of the invention.
