AS P I RATEU R BALAI AVEC SU CEU R ARTIC U LE AS P I R BRUSH WITH R E S
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. II 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. The present invention generally relates to a vacuum cleaner comprising a suction nozzle, and in particular a vacuum cleaner broom whose nozzle is articulated relative to the rest of the body of the vacuum cleaner broom to provide a high mobility during use. It is known in the prior art joints for vacuum cleaners and their nozzle, such as that presented in DE3913419, which discloses a universal joint type joint. In return, this system has the disadvantage of strongly deforming the hose forming the air duct between a nozzle and a fan motor housed in the body of a vacuum cleaner, which can lead to premature failures during large displacements angular. In addition, the system presented with link strings 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. The document US8627545 has meanwhile a broom vacuum with an articulated nozzle, but the movement of the body with its handle is limited, especially around a horizontal axis, and this device can not go to bed completely to go clean under a piece of furniture or under a bed for example.
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 meet the disadvantages of the documents of the prior art mentioned above and in particular, first of all, to propose a vacuum cleaner with an articulated nozzle, and whose articulation remains simple and can allow large angular movements, without strongly soliciting the constituent parts of the air circuit.
Pour cela un premier aspect de l'invention concerne un aspirateur balai comprenant : For this a first aspect of the invention relates to a vacuum cleaner comprising:
- 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, a vacuum cleaner body comprising suction means and a manipulation interface for a user, a nozzle arranged to be in contact with a floor to be cleaned and articulated with respect to the vacuum body,
- 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 :  an air circuit between the suction means and the nozzle and comprising a first deformable air duct with a first end connected to the nozzle, characterized:
- 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, - In that the sweeper vacuum cleaner comprises at least one piece of ball joint mounted in ball joint with respect to the vacuum body and on which is embarked a second end of the first deformable air duct,
- 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. 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. and in that the air circuit comprises at least a second deformable air duct, at least partially contained in the patella part, and connecting said second end on a portion of the air circuit of the vacuum cleaner body . The sweeping vacuum cleaner according to the present implementation therefore comprises a nozzle articulated on the vacuum cleaner body, but with a patella piece mounted in a ball joint relative to the vacuum cleaner body and a deformable air duct on each side of this nozzle. patella piece. The first deformable air duct is arranged between the patella piece and the nozzle, and the second deformable air duct is arranged between the patella piece and the vacuum body. Consequently, the patella piece, free with respect to the vacuum cleaner body, will be able to "follow" the movements of the nozzle, and as it is mounted between the first and second deformable air ducts, it will make a relative displacement. compared to the vacuum cleaner body less than that of the nozzle. Thus during a deflection of the nozzle, the deformation is distributed between the first and second deformable air duct, which limits the deformations imposed on each. Advantageously, the vacuum cleaner body has an elongated shape along a longitudinal axis passing through the ball joint, the brush vacuum cleaner comprises at least a first articulation between the nozzle and the vacuum cleaner body, with a rod mounted relative to vacuum cleaner body according to a pivot connection, for pivoting about a connecting rod axis, a projection in a plane containing the longitudinal axis is inclined relative to the longitudinal axis. Such a construction with the connecting rod mounted between the nozzle and the vacuum cleaner body separates the movement of the nozzle 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). 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 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 second deformable air duct). Advantageously, the projection of the rod axis in a plane containing the longitudinal axis is inclined with respect to the latter in an angular range 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 rod axis in a plane containing the longitudinal axis is inclined relative to the latter in an angular range from 35 ° to 45 °. This implementation makes it possible to have a good performance between the movement printed 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 about which the connecting rod is mounted to pivot about the connecting rod axis, the second deformable air duct having a passage section with at least one characteristic dimension, and the connecting rod shaft is offset from the longitudinal axis 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. 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. Avantageusement, la bielle comprend deux bras formant une ouverture, et le premier conduit d'air déformable passe au travers de l'ouverture. In other words, in general, the first joint is not on the longitudinal axis, or in said at least one patella piece. Advantageously, the brush vacuum cleaner comprises at least a second articulation between the connecting rod and the nozzle, with the connecting rod mounted relative to the nozzle according to a nozzle pivot connection, for pivoting about a nozzle axis parallel to the ground to be cleaned when the Squeegee is in plane contact with the floor to be cleaned. 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 avoids all contacts between the connecting rod and the first deformable air duct, to avoid wear or friction.
Avantageusement, chaque bras est monté en liaison pivot sur le suceur, selon l'axe de suceur. Advantageously, each arm is pivotally mounted on the nozzle, along the nozzle 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. Avantageusement, le premier conduit d'air déformable est un tube flexible. Advantageously, the rod can pivot relative to the nozzle at an angle greater than 70 ° and preferably at an angle greater than 90 °, to allow to bring the longitudinal axis parallel to the floor to be cleaned when the nozzle is in plane contact with the floor to clean. The user can then easily "flatten" the vacuum cleaner broom to clean the floor under a piece of furniture or a bed for example. 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. Avantageusement, le deuxième conduit d'air déformable est au moins partiellement formé par la pièce de rotule. Advantageously, the second deformable air duct is a flexible tube at least partially arranged in the patella piece. Advantageously, the second deformable air duct is at least partially formed by the patella piece.
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 patella piece. According to this implementation, there is a single piece for these two elements, and it is conceivable to produce such a part with a bi-material molding operation: a flexible material for producing the first deformable air duct and a rigid material for the patella part portion.
Avantageusement, le premier conduit d'air déformable et le deuxième conduit d'air déformable sont intégralement formés avec la pièce de rotule Advantageously, the first deformable air duct and the second deformable air duct are integrally formed with the patella piece
D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation de l'invention donné à titre d'exemple nullement limitatif et illustré par les dessins annexés, dans lesquels : - la figure 1 représente une vue isométrique d'un aspirateur balai selon l'invention, comprenant un corps d'aspirateur et un suceur, articulé par rapport au corps d'aspirateur ; Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the appended drawings, in which: - Figure 1 shows an isometric view of a vacuum cleaner brush according to the invention, comprising a vacuum cleaner body and a nozzle, articulated relative to the vacuum body;
- la figure 2 représente une vue détaillée du suceur de la figure 1 ; - Figure 2 shows a detailed view of the nozzle of Figure 1;
- la figure 3 représente une vue en coupe de la liaison entre le corps d'aspirateur et le suceur de la figure 1 . - Figure 3 shows a sectional view of the connection between the vacuum body and the nozzle of Figure 1.
La figure 1 représente un aspirateur balai comprenant un corps d'aspirateur 10 et un suceur 20, articulé par rapport au corps d'aspirateur 10 et agencé pour être en contact avec un sol à nettoyer. Le corps d'aspirateur 10 comprend une interface de manipulation 12 pour un utilisateur (une poignée), des moyens d'aspiration 1 1 (un moto-ventilateur électrique par exemple) et un tube d'aspiration 13 longiligne qui définit un axe longitudinal (L) du corps d'aspirateur 10. Figure 1 shows a vacuum cleaner comprising a suction body 10 and a nozzle 20, articulated relative to the vacuum 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-fan for example) and an elongated 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 1 1 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 relative to the vacuum body 10 and is connected to the suction means 1 1 by an air circuit. Indeed, the nozzle Typically comprises at least one suction slot facing the floor to be cleaned and connected to the suction means to allow impurities from the soil to be conveyed to a collection tank or a filter of the sweeper. In order to follow the movements of the nozzle 20, the vacuum cleaner includes a swivel piece to allow the air circuit to effectively connect the nozzle to the vacuum body 10, as will be described in Figures 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. Si on prend le corps d'aspirateur 10 comme référence, alors la bielleIndeed, the nozzle 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 about a rod axis ( B). Finally, the connecting rod 41 is connected to the nozzle 20 by a second pivot joint to enable it to pivot about the nozzle axis (S), which is parallel to the floor to be cleaned when the nozzle is in contact with the latter. If we take the vacuum cleaner body 10 as a reference, then the connecting rod
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). 41 engages the nozzle 20 and the latter can rotate relative to the vacuum body 10 around the connecting rod axis (B) and around the nozzle axis (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 nozzle 20 as a reference (when in contact with the soil to be cleaned), then the vacuum body 10 can pivot about the connecting rod axis (B) and around the nozzle axis ( S), via the connecting rod 41. The rotation of the connecting rod 41 around the axis of the nozzle (S) can be done over a large angular range, greater than 70 ° and preferably greater than 90 °, to allow "to lay" the vacuum cleaner broom 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. 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. 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. 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 combination of the first hinge pivot about the connecting rod axis (B) and the second hinge pin pivot (S), implies that the air circuit comprises deformable portions or ducts to follow the movements of the nozzle 20. In a general manner in the present application, deformable portion or duct of the air circuit is understood to mean a part of this air circuit whose shape varies under the simple request of the user when he handles with normal forces. As mentioned above, one of the aims of the present invention is to allow large deflections of the nozzle 20 relative to the vacuum body 10, while ensuring limited deformations to the deformable portions or ducts of the invention. air circuit, to guarantee their integrity and longevity. 2 shows a detailed view of the nozzle 20 (shown without outer cover, to improve understanding), on which we see the end piece 13a on which is mounted the connecting rod 41 pivot about the connecting rod axis (B), via a connecting rod shaft 42, visible in FIG.
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 nozzle 20, to pivot about the nozzle axis (S), and a first deformable air duct 51 connects the nozzle 20 to a ball member 61, better visible in the figure 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 1 1 . 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). 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 entraîner la première extrémité du deuxième conduit d'air déformable 52 pour le déformer. FIG. 3 shows a section of the connection between the vacuum cleaner body 10 and the nozzle 20. The ball piece 61 is seen in detail and is mounted in a ball joint with respect to the end piece 13a, and therefore with respect to to the vacuum body 10. The ball portion 61 receives the end of the first deformable air duct 51, and a second deformable air duct 52 is arranged in the ball portion 61 to connect the first air duct deformable 51 with the suction tube 13 and thus to the suction means 1 1. In other words, the first deformable air duct 51 comprises two ends: a first (not visible FIG. 3) linked or embarked on the nozzle 20 and a second one linked or embarked on the patella piece 61. As for the second deformable air duct 52, it also comprises two ends: a first linked or embarked on the patella piece 61 and a second connected to the end piece 13a (and thus to the vacuum body). During a movement (pivoting about the connecting rod axis (B) or around the nozzle axis (S)) of the nozzle 20 relative to the vacuum body 10, the first deformable air duct 51 is therefore drive the ball portion 61, which will in turn drive the first end of the second deformable air duct 52 to deform.
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 piece inserted between the two deformable air ducts 51 and 52 distributes the deformation on each of these two deformable air ducts, which limits the deformation of each, and thus 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. Figure 3 also shows the connecting rod axis (B) which is inclined relative to the longitudinal axis (L). It should be noted that this implementation with the two axes (L) and (B) coplanar is preferred, but that the invention generally proposes to have 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 rod axis (B) is inclined with respect to the longitudinal axis (L) in a range of values from 35 ° to 45 °, to have a good performance between the printed movement to the vacuum body 10 by the the user (through the handling interface 12) and the rotational movement of the nozzle 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. 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. 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 make room for the ball portion 61, and also to allow to "lay" the broom vacuum on the floor. In the present implementation, the connecting rod shaft 42 is integrally formed with the connecting rod 41, but it is conceivable to have 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. Finally, returning to FIG. 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 external 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 conceivable to use flexible pipes for example. In addition, it is conceivable to produce in one piece the ball portion 61 and the first deformable air duct 51. It is also conceivable to produce in one piece the second deformable air duct 52, the swivel 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 distinct from the ball portion 61, it is possible to envisage using a sealed ball joint connection, and the second deformable air duct would be formed by the ball joint piece 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. 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 conceivable to make the piece of ball 61 of "rigid" plastic material such as polyoxymethylene (or polyformaldehyde), acronym POM, or acrylonitrile butadiene styrene also called ABS. The deformable air ducts 51 and 52 may 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 frame can be provided in the deformable air ducts. It is also conceivable to make a single piece (piece of ball joint with sleeves and duct (s) of deformable air (s)) in bi-injection or 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 the scope of the invention defined by the appended claims. For example, the ball portion 61 is mounted in ball joint connection in the end piece 13a so that the patella part 61 then corresponds to a male ball joint part, but other forms can be envisaged for making a ball joint connection, and in particular, the ball portion 61 could be a female part.
