Description

La présente invention concerne de manière générale un aspirateur balai comprenant un suceur, et en particulier un aspirateur balai dont le suceur est articulé par rapport au reste du corps de l'aspirateur balai pour proposer une grande mobilité lors de l'utilisation.The present invention generally relates to a broom vacuum cleaner comprising a nozzle, and in particular a broom vacuum cleaner whose nozzle is articulated with respect to the rest of the body of the broom vacuum cleaner to provide great mobility during use.

Il est connu dans l'art antérieur des articulations pour les aspirateurs et leur suceur, telles que celle présentée dans le document DE3913419 , qui divulgue une articulation de type joint de cardan. En contrepartie, ce système présente notamment l'inconvénient de déformer fortement le flexible formant le conduit d'air entre un suceur et un moto ventilateur logé dans le corps d'un aspirateur balai, ce qui peut conduire à des ruptures prématurées lors de grands déplacements angulaires. De plus, le système présenté avec des chaînes de liaison est compliqué.It is known in the prior art joints for vacuum cleaners and their nozzle, such as that presented in the document DE3913419 , which discloses a universal joint type articulation. On the other hand, this system has in particular the disadvantage of greatly deforming the hose forming the air duct between a nozzle and a fan motor housed in the body of a stick vacuum cleaner, which can lead to premature ruptures during large movements. angular. Moreover, the presented system with linking chains is complicated.

Le document US8627545 présente quant à lui un aspirateur balai avec un suceur articulé, mais dont le débattement du corps avec sa poignée est limité, notamment autour d'un axe horizontal, et cet appareil ne peut pas se coucher complètement pour aller nettoyer sous un meuble ou sous un lit par exemple. Le document EP2621323A1 décrit quant à lui un aspirateur balai selon le préambule de la revendication 1.The document US8627545 presents a stick vacuum cleaner with an articulated nozzle, but whose movement of the body with its handle is limited, in particular around a horizontal axis, and this device cannot lie down completely to clean under a piece of furniture or under a bed for example. The document EP2621323A1 describes a stick vacuum cleaner according to the preamble of claim 1.

Un but de la présente invention est de répondre aux inconvénients des documents de l'art antérieur mentionnés ci-dessus et en particulier, tout d'abord, de proposer un aspirateur balai avec un suceur articulé, et dont l'articulation reste simple et peut autoriser de grands mouvements angulaires, sans pour autant solliciter fortement les pièces constitutives du circuit d'air.An object of the present invention is to respond to the drawbacks of the documents of the prior art mentioned above and in particular, first of all, to propose a stick vacuum cleaner with an articulated nozzle, and whose articulation remains simple and can allow large angular movements, without however strongly stressing the constituent parts of the air circuit.

Pour cela un premier aspect de l'invention concerne un aspirateur balai comprenant :

  • un corps d'aspirateur comprenant des moyens d'aspiration et une interface de manipulation pour un utilisateur,
  • un suceur agencé pour être en contact avec un sol à nettoyer et articulé par rapport au corps d'aspirateur,
  • un circuit d'air entre les moyens d'aspiration et le suceur et comprenant un premier conduit d'air déformable avec une première extrémité liée au suceur, caractérisé :
  • en ce que l'aspirateur balai comprend au moins une pièce de rotule montée en liaison rotule par rapport au corps d'aspirateur et sur laquelle est embarquée une deuxième extrémité du premier conduit d'air déformable,
  • et en ce que le circuit d'air comprend au moins un deuxième conduit d'air déformable, au moins partiellement contenu dans la pièce de rotule, et raccordant ladite deuxième extrémité embarquée à une portion du circuit d'air du corps d'aspirateur. L'aspirateur balai selon la présente mise en œuvre comprend donc un suceur articulé sur le corps d'aspirateur, mais avec une pièce de rotule montée en rotule par rapport au corps d'aspirateur et un conduit d'air déformable de chaque côté de cette pièce de rotule. Le premier conduit d'air déformable est agencé entre la pièce de rotule et le suceur, et le deuxième conduit d'air déformable est agencé entre la pièce de rotule et le corps d'aspirateur. En conséquence, la pièce de rotule, libre par rapport au corps d'aspirateur, va pouvoir "suivre" les mouvements du suceur, et comme elle est montée entre le premier et le deuxième conduit d'air déformable, elle va effectuer un déplacement relatif par rapport au corps d'aspirateur inférieur à celui du suceur. Ainsi lors d'un débattement du suceur, la déformation est répartie entre le premier et le deuxième conduit d'air déformable, ce qui limite les déformations imposées à chacun.
For this, a first aspect of the invention relates to a stick vacuum cleaner comprising:
  • a vacuum cleaner body comprising suction means and a handling interface for a user,
  • a nozzle arranged to be in contact with a floor to be cleaned and articulated with respect to the vacuum cleaner body,
  • an air circuit between the suction means and the squeegee and comprising a first deformable air duct with a first end linked to the squeegee, characterized:
  • in that the stick vacuum cleaner comprises at least one ball joint piece mounted in a ball joint with respect to the vacuum cleaner body and on which is embedded a second end of the first deformable air duct,
  • and in that the air circuit comprises at least one second deformable air duct, at least partially contained in the ball joint part, and connecting said second on-board end to a portion of the air circuit of the vacuum cleaner body. The broom vacuum cleaner according to the present implementation therefore comprises a nozzle articulated on the vacuum cleaner body, but with a ball joint piece mounted in a ball joint with respect to the vacuum cleaner body and a deformable air duct on each side of this ball joint. The first deformable air duct is arranged between the ball joint part and the nozzle, and the second deformable air duct is arranged between the ball joint part and the vacuum cleaner body. Consequently, the ball joint part, free with respect to the vacuum cleaner body, will be able to "follow" the movements of the squeegee, and as it is mounted between the first and the second deformable air duct, it will perform a relative movement compared to the vacuum cleaner body lower than that of the squeegee. Thus during movement of the squeegee, the deformation is distributed between the first and the second deformable air duct, which limits the deformations imposed on each.

Avantageusement, le corps d'aspirateur présente une forme allongée le long d'un axe longitudinal passant par la liaison rotule, l'aspirateur balai comprend au moins une première articulation entre le suceur et le corps d'aspirateur, avec une bielle montée par rapport au corps d'aspirateur selon une liaison pivot, pour pivoter autour d'un axe de bielle dont une projection dans un plan contenant l'axe longitudinal est inclinée par rapport à l'axe longitudinal. Une telle construction avec la bielle montée entre le suceur et le corps d'aspirateur permet de séparer le mouvement du suceur avec celui du circuit d'air comprenant le premier conduit d'air déformable et le deuxième conduit d'air déformable.Advantageously, the vacuum cleaner body has an elongated shape along a longitudinal axis passing through the ball joint, the broom vacuum cleaner comprises at least a first joint between the nozzle and the vacuum cleaner body, with a connecting rod mounted relative to the vacuum cleaner body according to a pivot connection, to pivot around a connecting rod axis, one projection of which in a plane containing the longitudinal axis is inclined with respect to the longitudinal axis. Such a construction with the connecting rod mounted between the squeegee and the vacuum cleaner body makes it possible to separate the movement of the squeegee with that of the air circuit comprising the first deformable air duct and the second deformable air duct.

Avantageusement, le corps d'aspirateur comprend un tube d'aspiration allongé définissant l'axe longitudinal, avec les moyens d'aspiration et l'interface de manipulation agencés à une première extrémité du tube d'aspiration, et le suceur agencé à une deuxième extrémité du tube d'aspiration (le suceur étant relié au tube d'aspiration par l'intermédiaire du premier et du deuxième conduit d'air déformable).Advantageously, the vacuum cleaner body comprises an elongated suction tube defining the longitudinal axis, with the suction means and the manipulation interface arranged at a first end of the suction tube, and the nozzle arranged at a second end of the suction tube (the nozzle being connected to the suction tube via the first and the second deformable air duct).

Avantageusement, la projection de l'axe de bielle dans un plan contenant l'axe longitudinal est inclinée par rapport à ce dernier dans une plage angulaire allant de 20° à 60°.Advantageously, the projection of the connecting rod axis in a plane containing the longitudinal axis is inclined with respect to the latter in an angular range ranging from 20° to 60°.

Avantageusement, la projection de l'axe de bielle dans un plan contenant l'axe longitudinal est inclinée par rapport à ce dernier dans une plage angulaire allant de 35° à 45°. Cette mise en œuvre permet d'avoir un bon rendement entre le mouvement imprimé au corps d'aspirateur par l'utilisateur (par le biais de l'interface de manipulation) et le mouvement de rotation du suceur autour de l'axe de bielle.Advantageously, the projection of the connecting rod axis in a plane containing the longitudinal axis is inclined with respect to the latter in an angular range ranging from 35° to 45°. This implementation makes it possible to have a good yield between the movement imparted to the vacuum cleaner body by the user (through the handling interface) and the rotational movement of the nozzle around the connecting rod axis.

Avantageusement, ladite au moins une première articulation comprend au moins un arbre de bielle autour duquel est montée la bielle pour pivoter autour de l'axe de bielle, le deuxième conduit d'air déformable présente une section de passage avec au moins une dimension caractéristique, et l'arbre de bielle est déporté de l'axe longitudinal d'une distance au moins supérieure à la moitié de ladite au moins une dimension caractéristique. L'arbre de bielle est déporté du circuit d'air, ce qui laisse la place d'agencer l'articulation rotule et la première articulation (le pivot de bielle) sans compliquer ou miniaturiser les pièces.Advantageously, said at least one first articulation comprises at least one connecting rod shaft around which the connecting rod is mounted to pivot around the connecting rod axis, the second deformable air duct has a passage section with at least one characteristic dimension, and the connecting rod shaft is offset from the longitudinal axis by a distance at least greater than half of said at least one characteristic dimension. The connecting rod shaft is offset from the air circuit, which leaves room to arrange the ball joint and the first joint (the connecting rod pivot) without complicating or miniaturizing the parts.

Avantageusement, le deuxième conduit d'air déformable présente une section circulaire, et l'arbre de bielle est déporté de l'axe longitudinal d'une distance supérieure au rayon de la section du deuxième conduit d'air déformable.Advantageously, the second deformable air duct has a circular section, and the connecting rod shaft is offset from the longitudinal axis of a distance greater than the radius of the section of the second deformable air duct.

Autrement dit, de manière générale, la première articulation n'est pas sur l'axe longitudinal, ni dans ladite au moins une pièce de rotule.In other words, in general, the first articulation is not on the longitudinal axis, nor in said at least one ball joint part.

Avantageusement, l'aspirateur balai comprend au moins une deuxième articulation entre la bielle et le suceur, avec la bielle montée par rapport au suceur selon une liaison pivot de suceur, pour pivoter autour d'un axe de suceur parallèle au sol à nettoyer lorsque le suceur est en contact plan avec le sol à nettoyer.Advantageously, the stick vacuum cleaner comprises at least a second articulation between the connecting rod and the squeegee, with the connecting rod mounted relative to the squeegee according to a squeegee pivot connection, to pivot around a squeegee axis parallel to the floor to be cleaned when the squeegee is in flat contact with the floor to be cleaned.

Avantageusement, la bielle comprend deux bras formant une ouverture, et le premier conduit d'air déformable passe au travers de l'ouverture.Advantageously, the connecting rod comprises two arms forming an opening, and the first deformable air duct passes through the opening.

Avantageusement, l'ouverture présente une largeur allant de 1.2 à 1.5 fois une dimension extérieure du premier conduit d'air déformable. Cette mise en œuvre permet d'éviter tous les contacts entre la bielle et le premier conduit d'air déformable, afin d'éviter toute usure ou frottement.Advantageously, the opening has a width ranging from 1.2 to 1.5 times an external dimension of the first deformable air duct. This implementation makes it possible to avoid all contact between the connecting rod and the first deformable air duct, in order to avoid any wear or friction.

Avantageusement, chaque bras est monté en liaison pivot sur le suceur, selon l'axe de suceur.Advantageously, each arm is mounted in a pivot connection on the squeegee, along the squeegee axis.

Avantageusement, la bielle peut pivoter par rapport au suceur d'un angle supérieur à 70° et préférentiellement d'un angle supérieur à 90°, pour permettre d'amener l'axe longitudinal parallèle au sol à nettoyer lorsque le suceur est en contact plan avec le sol à nettoyer. L'utilisateur peut alors aisément "mettre à plat" l'aspirateur balai pour nettoyer le sol sous un meuble ou un lit par exemple.Advantageously, the connecting rod can pivot relative to the squeegee by an angle greater than 70° and preferably by an angle greater than 90°, to make it possible to bring the longitudinal axis parallel to the ground to be cleaned when the squeegee is in flat contact with the floor to be cleaned. The user can then easily "flatten" the stick vacuum cleaner to clean the floor under a piece of furniture or a bed, for example.

Avantageusement, le premier conduit d'air déformable est un tube flexible.Advantageously, the first deformable air duct is a flexible tube.

Avantageusement, le deuxième conduit d'air déformable est un tube flexible au moins partiellement agencé dans la pièce de rotule.Advantageously, the second deformable air duct is a flexible tube at least partially arranged in the ball joint part.

Avantageusement, le deuxième conduit d'air déformable est au moins partiellement formé par la pièce de rotule.Advantageously, the second deformable air duct is at least partially formed by the ball joint part.

Avantageusement, le premier conduit d'air déformable est intégralement formé avec la pièce de rotule. Selon cette mise en œuvre, on a une seule pièce pour ces deux éléments, et on peut envisager de réaliser une telle pièce avec une opération de moulage bi-matière : une matière flexible pour réaliser le premier conduit d'air déformable et une matière rigide pour la portion pièce de rotule.Advantageously, the first deformable air duct is integrally formed with the ball joint part. According to this implementation, there is a single part for these two elements, and it is possible to envisage producing such a part with a bi-material molding operation: a flexible material to produce the first deformable air duct and a rigid material for the ball joint part.

Avantageusement, le premier conduit d'air déformable et le deuxième conduit d'air déformable sont intégralement formés avec la pièce de rotuleAdvantageously, the first deformable air duct and the second deformable air duct are integrally formed with the ball joint part

Le corps d'aspirateur 10 comprend une interface de manipulation 12 pour un utilisateur (une poignée), des moyens d'aspiration 11 (un moto-ventilateur électrique par exemple) et un tube d'aspiration 13 longiligne qui définit un axe longitudinal (L) du corps d'aspirateur 10.The figure 1 represents a broom vacuum cleaner comprising a vacuum cleaner body 10 and a nozzle 20, articulated with respect to the vacuum cleaner body 10 and arranged to be in contact with a floor to be cleaned. The vacuum cleaner body 10 comprises a handling interface 12 for a user (a handle), suction means 11 (an electric motor-driven fan for example) and a slender suction tube 13 which defines a longitudinal axis (L ) of the vacuum cleaner body 10.

Le suceur 20 est articulé par rapport au corps d'aspirateur 10 et il est connecté aux moyens d'aspiration 11 par un circuit d'air. En effet, le suceur 20 comprend typiquement au moins une fente d'aspiration en regard du sol à nettoyer et connectée aux moyens d'aspiration pour permettre d'entraîner des impuretés du sol vers un réservoir de collecte ou un filtre de l'aspirateur balai. Afin de suivre les débattements du suceur 20, l'aspirateur balai comprend une pièce de rotule pour permettre au circuit d'air de relier efficacement le suceur au corps d'aspirateur 10, comme cela sera décrit aux figures 2 et 3.The nozzle 20 is articulated with respect to the vacuum cleaner body 10 and it is connected to the suction means 11 by an air circuit. Indeed, the sucker 20 typically comprises at least one suction slot facing the floor to be cleaned and connected to the suction means to allow impurities from the floor to be drawn into a collection tank or a filter of the stick vacuum cleaner. In order to follow the deflections of the squeegee 20, the stick vacuum cleaner comprises a ball joint part to allow the air circuit to effectively connect the squeegee to the vacuum cleaner body 10, as will be described in figure 2 and 3 .

En effet, le suceur 20 est relié au corps d'aspirateur 10 par une bielle 41 connectée à une pièce extrémale 13a du tube d'aspiration 13 par une première articulation pivot qui permet de pivoter la bielle 41 autour d'un axe de bielle (B). Enfin, la bielle 41 est reliée au suceur 20 par une deuxième articulation pivot pour lui permettre de pivoter autour de l'axe de suceur (S), qui est parallèle au sol à nettoyer lorsque le suceur est en contact avec ce dernier.Indeed, the squeegee 20 is connected to the vacuum cleaner body 10 by a connecting rod 41 connected to an end piece 13a of the suction tube 13 by a first pivot joint which makes it possible to pivot the connecting rod 41 around a connecting rod axis ( B). Finally, the connecting rod 41 is connected to the squeegee 20 by a second pivot joint to enable it to pivot around the squeegee axis (S), which is parallel to the floor to be cleaned when the squeegee is in contact with the latter.

Si on prend le corps d'aspirateur 10 comme référence, alors la bielle 41 embarque le suceur 20 et ce dernier peut pivoter par rapport au corps d'aspirateur 10 autour de l'axe de bielle (B) et autour de l'axe de suceur (S).If we take the vacuum cleaner body 10 as a reference, then the connecting rod 41 embeds the nozzle 20 and the latter can pivot relative to the vacuum cleaner body 10 around the connecting rod axis (B) and around the axis of sucker (S).

Si on prend le suceur 20 comme référence (lorsqu'il est en contact avec le sol à nettoyer), alors le corps d'aspirateur 10 peut pivoter autour de l'axe de bielle (B) et autour de l'axe de suceur (S), par l'intermédiaire de la bielle 41. La rotation de la bielle 41 autour de l'axe de suceur (S) peut se faire sur une grande plage angulaire, supérieure à 70° et préférentiellement supérieure à 90°, pour permettre de "coucher" l'aspirateur balai sur le sol (c'est-à-dire amener l'axe longitudinal (L) quasiment parallèle au sol) pour nettoyer sous un meuble par exemple.If we take the squeegee 20 as a reference (when it is in contact with the floor to be cleaned), then the vacuum cleaner body 10 can pivot around the connecting rod axis (B) and around the squeegee axis ( S), via the connecting rod 41. The rotation of the connecting rod 41 around the squeegee axis (S) can be done over a large angular range, greater than 70° and preferably greater than 90°, to allow to "lay" the stick vacuum cleaner on the ground (that is to say bring the longitudinal axis (L) almost parallel to the ground) to clean under a piece of furniture for example.

La combinaison de la première articulation pivot autour de l'axe de bielle (B) et de la deuxième articulation pivot d'axe de suceur (S), implique que le circuit d'air comprenne des portions ou des conduits déformables pour suivre les débattements du suceur 20.The combination of the first pivot joint around the connecting rod axis (B) and the second nozzle axis pivot joint (S) implies that the air circuit comprises deformable portions or ducts to follow the deflections of the sucker 20.

D'une manière générale dans la présente demande, on entend par portion ou conduit déformable du circuit d'air une partie de ce circuit d'air dont la forme varie sous la simple sollicitation de l'utilisateur lorsqu'il manipule avec des efforts normaux le corps d'aspirateur 10.In general, in the present application, the term deformable portion or duct of the air circuit means a part of this air circuit whose shape varies under the simple stress of the user when handling with normal efforts. the vacuum cleaner body 10.

Comme évoqué ci-dessus, un des buts de la présente invention est de permettre de grands débattements du suceur 20 par rapport au corps d'aspirateur 10, tout en assurant des déformations limitées aux portions ou conduits déformables du circuit d'air, afin de garantir leur intégrité et leur longévité.As mentioned above, one of the aims of the present invention is to allow large deflections of the nozzle 20 with respect to the vacuum cleaner body 10, while ensuring limited deformations to the deformable portions or ducts of the air circuit, in order to guarantee their integrity and longevity.

La figure 2 représente une vue détaillée du suceur 20 (représenté sans capot extérieur, pour améliorer la compréhension), sur laquelle on voit la pièce extrémale 13a sur laquelle est montée la bielle 41 en pivot autour de l'axe de bielle (B), par l'intermédiaire d'un arbre de bielle 42, visible figure 3.The figure 2 shows a detailed view of the squeegee 20 (shown without an outer cover, to improve understanding), on which we see the end piece 13a on which the connecting rod 41 is pivotally mounted around the connecting rod axis (B), by the intermediate of a connecting rod shaft 42, visible picture 3 .

La bielle 41 est montée en pivot sur le suceur 20, pour pivoter autour de l'axe de suceur (S), et un premier conduit d'air déformable 51 relie le suceur 20 à une pièce de rotule 61, mieux visible sur la figure 3.The connecting rod 41 is pivotally mounted on the squeegee 20, to pivot around the squeegee axis (S), and a first deformable air duct 51 connects the squeegee 20 to a ball joint 61, better visible on the picture 3 .

La figure 3 montre en effet une coupe de la liaison entre le corps d'aspirateur 10 et le suceur 20. On voit en détail la pièce de rotule 61 qui est montée en liaison rotule par rapport à la pièce extrémale 13a, et donc par rapport au corps d'aspirateur 10. La pièce de rotule 61 reçoit l'extrémité du premier conduit d'air déformable 51, et un deuxième conduit d'air déformable 52 est agencé dans la pièce de rotule 61 pour connecter le premier conduit d'air déformable 51 avec le tube d'aspiration 13 et donc aux moyens d'aspiration 11.The picture 3 indeed shows a section of the connection between the vacuum cleaner body 10 and the nozzle 20. We see in detail the ball joint part 61 which is mounted in ball joint with respect to the extremal part 13a, and therefore with respect to the body of vacuum cleaner 10. The ball joint piece 61 receives the end of the first deformable air duct 51, and a second deformable air duct 52 is arranged in the ball joint piece 61 to connect the first deformable air duct 51 with the suction tube 13 and therefore to the suction means 11.

En d'autres termes, le premier conduit d'air déformable 51 comprend deux extrémités : une première (non visible figure 3) liée ou embarquée sur le suceur 20 et une deuxième liée ou embarquée sur la pièce de rotule 61. Quant au deuxième conduit d'air déformable 52, il comprend également deux extrémités : une première liée ou embarquée sur la pièce de rotule 61 et une deuxième liée à la pièce extrémale 13a (et donc au corps d'aspirateur).In other words, the first deformable air duct 51 comprises two ends: a first (not visible picture 3 ) linked or embedded on the nozzle 20 and a second linked or embedded on the ball joint part 61. As for the second deformable air duct 52, it also comprises two ends: a first linked or embedded on the ball joint part 61 and a second linked to the extremal piece 13a (and therefore to the vacuum cleaner body).

Lors d'un mouvement (pivotement autour de l'axe de bielle (B) ou autour de l'axe de suceur (S)) du suceur 20 par rapport au corps d'aspirateur 10, le premier conduit d'air déformable 51 va donc entraîner la pièce de rotule 61, qui va à son tour entrainer la première extrémité du deuxième conduit d'air déformable 52 pour le déformer.During a movement (pivoting around the connecting rod axis (B) or around the squeegee axis (S)) of the squeegee 20 relative to the vacuum cleaner body 10, the first deformable air duct 51 goes therefore drive the ball joint 61, which will in turn drive the first end of the second deformable air duct 52 to deform it.

En conséquence, la pièce de rotule intercalée entre les deux conduits d'air déformables 51 et 52 permet de répartir la déformation sur chacun de ces deux conduits d'air déformables, ce qui limite la déformation de chacun, et cela évite donc usure et/ou casse prématurée de ces conduits d'air déformables.Consequently, the ball joint part inserted between the two deformable air ducts 51 and 52 makes it possible to distribute the deformation over each of these two deformable air ducts, which limits the deformation of each, and this therefore avoids wear and/or or premature breakage of these deformable air ducts.

La figure 3 représente également l'axe de bielle (B) qui est donc incliné par rapport à l'axe longitudinal (L). Il est à noter que cette mise en œuvre avec les deux axes (L) et (B) coplanaires est préférée, mais que l'invention propose de manière générale d'avoir un axe de bielle (B) dont la projection, dans un plan contenant l'axe longitudinal (L), est inclinée par rapport à l'axe longitudinal (L). Autrement dit, l'axe longitudinal (L) et l'axe de bielle (B) ne sont pas forcément coplanaires.The picture 3 also represents the connecting rod axis (B) which is therefore inclined with respect to the longitudinal axis (L). It should be noted that this implementation with the two coplanar axes (L) and (B) is preferred, but that the invention generally proposes having a connecting rod axis (B) whose projection, in a plane containing the longitudinal axis (L), is inclined with respect to the longitudinal axis (L). In other words, the longitudinal axis (L) and the connecting rod axis (B) are not necessarily coplanar.

L'axe de bielle (B) est incliné par rapport à l'axe longitudinal (L) dans une plage de valeur allant de 35° à 45°, pour avoir un bon rendement entre le mouvement imprimé au corps d'aspirateur 10 par l'utilisateur (par le biais de l'interface de manipulation 12) et le mouvement de rotation du suceur 20 autour de l'axe de bielle (B).The connecting rod axis (B) is inclined with respect to the longitudinal axis (L) in a range of values ranging from 35° to 45°, to have a good yield between the movement imparted to the vacuum cleaner body 10 by the user (through the manipulation interface 12) and the rotational movement of the squeegee 20 around the connecting rod axis (B).

Par ailleurs, l'arbre de bielle 42 est déporté par rapport au deuxième conduit d'air déformable 52 et par rapport à l'axe longitudinal (L), afin de ménager de la place à la pièce de rotule 61, et aussi pour permettre de "coucher" l'aspirateur balai sur le sol. Dans la présente mise en œuvre, l'arbre de bielle 42 est intégralement formé avec la bielle 41, mais on peut envisager d'avoir deux pièces distinctes. Dans le détail, l'arbre de bielle 42 est monté en pivot directement dans la pièce extrémale 13a, et retenu dans cette dernière par un jonc élastique.Furthermore, the connecting rod shaft 42 is offset relative to the second deformable air duct 52 and relative to the longitudinal axis (L), in order to save space for the ball joint part 61, and also to allow to "lay" the stick vacuum cleaner on the floor. In the present implementation, the connecting rod shaft 42 is integrally formed with the connecting rod 41, but it is possible to envisage having two separate parts. In detail, the connecting rod shaft 42 is pivotally mounted directly in the end piece 13a, and retained in the latter by an elastic ring.

Enfin, de retour à la figure 2, on peut noter que la bielle 41 comprend deux bras, chacun monté en pivot sur le suceur 20, afin de présenter une ouverture de passage pour le premier conduit d'air déformable 51. De manière avantageuse, l'ouverture présente une largeur supérieure à 1.2-1.5 fois la dimension extérieure du premier conduit d'air déformable pour éviter tout contact et usure entre ces éléments.Finally, back to the figure 2 , it may be noted that the connecting rod 41 comprises two arms, each pivotally mounted on the nozzle 20, in order to present a passage opening for the first deformable air duct 51. Advantageously, the opening has a width greater than 1.2-1.5 times the outer dimension of the first deformable air duct to avoid any contact and wear between these elements.

En ce qui concerne le premier et le deuxième conduit d'air déformable 51 et 52, on peut envisager d'utiliser des tuyaux flexibles par exemple. De plus, on peut envisager de réaliser en une seule pièce la pièce de rotule 61 et le premier conduit d'air déformable 51. On peut aussi envisager de réaliser en une seule pièce le deuxième conduit d'air déformable 52, la pièce de rotule 61 et le premier conduit d'air déformable 51.As regards the first and the second deformable air duct 51 and 52, it is possible to envisage using flexible pipes for example. In addition, it is possible to envisage making the ball joint piece 61 and the first deformable air duct 51 in one piece. It is also possible to envisage making the second deformable air duct 52 in one piece, the ball joint piece 61 and the first deformable air duct 51.

Enfin, en alternative à un deuxième conduit d'air déformable distinct de la pièce de rotule 61, on peut envisager d'utiliser une liaison rotule étanche, et le deuxième conduit d'air déformable serait formé par la pièce de rotule 61 elle-même.Finally, as an alternative to a second deformable air duct separate from the ball joint part 61, it is possible to envisage using a sealed ball joint, and the second deformable air duct would be formed by the ball joint part 61 itself. .

On peut envisager de réaliser la pièce de rotule 61 en matière plastique "rigide" telle que du polyoxyméthylène (ou polyformaldéhyde), de sigle POM, ou en acrylonitrile butadiène styrène encore appelé ABS. Les conduits d'air déformables 51 et 52 peuvent être réalisés en élastomères thermoplastiques (TPE) comme du polyuréthane (TPU) ou en EPDM (éthylène-propylène-diène monomère) ou en polychlorure de vinyle ou chlorure de polyvinyle autrement appelé PVC. On peut prévoir une armature métal dans les conduits d'air déformables.It is possible to envisage making the ball joint part 61 out of "rigid" plastic material such as polyoxymethylene (or polyformaldehyde), with the acronym POM, or in acrylonitrile butadiene styrene also called ABS. The deformable air ducts 51 and 52 can be made of thermoplastic elastomers (TPE) such as polyurethane (TPU) or EPDM (ethylene-propylene-diene monomer) or polyvinyl chloride or polyvinyl chloride otherwise called PVC. A metal reinforcement can be provided in the deformable air ducts.

On peut aussi envisager de réaliser une pièce monobloc (pièce de rotule avec manchons et conduit(s) d'air déformable(s)) en bi-injection ou en opération de surmoulage.It is also possible to envisage making a one-piece part (ball joint part with sleeves and deformable air duct(s)) in bi-injection or in an overmolding operation.

On comprendra que diverses modifications et/ou améliorations évidentes pour l'homme du métier peuvent être apportées au mode de réalisation de l'invention décrit dans la présente description sans sortir du cadre de l'invention défini par les revendications annexées. Par exemple, la pièce de rotule 61 est montée en liaison rotule dans la pièce extrémale 13a ce qui fait que la pièce de rotule 61 correspond alors à une pièce de rotule mâle, mais on peut envisager d'autres formes pour réaliser une liaison rotule, et en particulier, la pièce de rotule 61 pourrait être une pièce femelle.It will be understood that various modifications and/or improvements obvious to those skilled in the art can be made to the embodiment of the invention described in the present description without departing from the scope of the invention defined by the appended claims. For example, the ball joint part 61 is mounted in a ball joint in the extremal part 13a which means that the ball joint part 61 then corresponds to a male ball joint part, but other shapes can be envisaged to achieve a ball joint, and in particular, the ball part 61 could be a female part.
