Description
Le domaine technique de l'invention est l'outillage pour le nettoyage de bassins, en particulier d'une piscine.The technical field of the invention is tools for cleaning basins, in particular a swimming pool.
On connaît les dispositifs de nettoyage, par exemple de type aspirateur, comportant un manche articulé, permettant de déplacer un outil de nettoyage, de type patin ou une brosse, destiné à être déplacé sur le sol. Dans de tels dispositifs, une pièce d'interface coudée est disposée entre le manche et l'outil de nettoyage.Cleaning devices are known, for example of the vacuum cleaner type, comprising an articulated handle, making it possible to move a cleaning tool, of the pad or brush type, intended to be moved on the floor. In such devices, an angled interface piece is disposed between the handle and the cleaning tool.
Lorsque l'outil de nettoyage repose sur le sol, sous l'effet d'une rotation du manche autour de son axe, une partie du mouvement de rotation est transférée à l'outil de nettoyage. La rotation de l'outil de nettoyage est en partie bloquée par le sol. Ainsi, le mouvement de rotation du manche se traduit par une orientation du balais le long du sol : vers la gauche lorsque le manche est tourné selon un sens anti-horaire, et vers la droite lorsque le manche est tourné vers le sens horaire. Cela permet de contrôler, à distance, l'orientation de l'outil de nettoyage, par une simple rotation du manche.When the cleaning tool rests on the floor, under the effect of a rotation of the handle about its axis, part of the rotational movement is transferred to the cleaning tool. The rotation of the cleaning tool is partially blocked by the floor. Thus, the rotational movement of the handle results in an orientation of the brush along the ground: to the left when the handle is turned anti-clockwise, and to the right when the handle is turned clockwise. This makes it possible to control, from a distance, the orientation of the cleaning tool, by a simple rotation of the handle.
Cependant, les dispositifs existants utilisent des pièces articulées compliquées, et relativement complexes à fabriquer, qui permettent une rotation selon deux axes de rotation.However, the existing devices use complicated articulated parts, and relatively complex to manufacture, which allow rotation along two axes of rotation.
Les inventeurs ont adapté le principe de fonctionnement décrit ci-dessus à un dispositif d'un nettoyage d'une piscine. Ils proposent une pièce d'interface de conception simple, peu onéreuse, pouvant être immergée, et permettant une orientation à distance d'un outil de nettoyage, à l'aide d'un manche.The inventors have adapted the operating principle described above to a device for cleaning a swimming pool.

La pièce d'interface 1 comporte une partie amont 10 reliée à une partie aval 20. La partie amont 10 est destinée à s'engager à l'intérieur du manche de préhension 30, comme décrit en lien avec la
La pièce d'interface 1 s'étend entre une extrémité proximale 11 et une extrémité distale 21. La pièce d'interface 1 comporte une articulation 2, permettant une rotation de la partie amont 10 relativement à la partie aval 20, autour d'un axe de rotation Δ. La pièce d'interface 1 comporte un coude 3, disposé entre l'articulation 2 et l'extrémité proximale 11. Le coude forme un angle α obtus. L'angle α est de préférence compris entre 100° et 170°, et de préférence entre 110° et 160°. La plage angulaire optimale est comprise entre 140° et 160°. Le coude 3 est formé dans la partie amont 10. L'angle α ainsi que les axes Δ1 et Δ2 sont représentés sur la
La pièce d'interface 1 est de préférence rigide. Elle peut être obtenue à partir d'un métal ou d'un plastique. Lorsqu'elle est en plastique, la pièce d'interface 1 peut par exemple être obtenue par moulage, ou par fabrication additive.The
La partie amont 10 s'étend, à partir de l'extrémité proximale 11, au moins jusqu'à l'articulation 2. La partie amont 10 comporte une portion rectiligne amont 12, adjacente de l'extrémité proximale 11. La portion rectiligne amont 12 s'étend, à partir de l'extrémité proximale 11, autour d'un axe amont Δ1. Dans l'exemple représenté, la portion rectiligne amont 12 est tubulaire. La portion rectiligne amont 12 est destinée à s'engager dans un manche de préhension 30. La portion rectiligne amont 12 peut également être inscrite dans une forme tubulaire. Quelle soit tubulaire ou inscrite dans une forme tubulaire, la portion rectiligne amont 12 définit un diamètre compris entre 1 et 10 cm.The
La partie aval 20 s'étend, à partir de l'extrémité distale 21, au moins jusqu'à l'articulation 2. La partie aval 20 comporte une portion rectiligne aval 22, adjacente de l'extrémité distale 21. La portion rectiligne aval 22 s'étend, à partir de l'extrémité distale, autour d'un axe Δ2 aval. La portion rectiligne aval 22 est de préférence tubulaire. Elle est destinée à être engagée autour d'un manche de liaison 42 de l'outil de nettoyage 40. Les axes amont et aval sont sécants. L'angle α formé par le coude 3 correspond à l'angle entre l'axe amont Δ1 et l'axe aval Δ2. Les axes amont et aval sont représentés sur les
La pièce d'interface 1 définit une partie orientable 4, s'étendant entre le coude 3 et l'extrémité aval 21. La partie orientable 4 comporte l'articulation 2. Ainsi, la partie orientable 4 comporte la partie aval 20 ainsi qu'une portion de la partie amont 10 s'étendant entre l'articulation 2 et le coude 3. Comme décrit par la suite, lors de l'utilisation de la pièce d'interface 1, la partie orientable 4 est destinée à orienter l'outil de nettoyage 40 relié à la pièce, sous l'effet d'une rotation de la partie amont 10 autour de l'axe de rotation amont Δ1. La partie orientable 4 est représentée sur les
Dans l'exemple représenté sur les
- la partie amont 10 est tubulaire de l'extrémité proximale 11
jusqu'à l'articulation 2 ; - la partie aval 20 est tubulaire de l'articulation 2 jusqu'à l'extrémité distale 21.
- the
upstream part 10 is tubular from theproximal end 11 to the joint 2; - the
downstream part 20 is tubular from the joint 2 to thedistal end 21.
Une telle configuration est préférée car elle est plus simple à fabriquer.Such a configuration is preferred because it is simpler to manufacture.
La partie aval 20 est de préférence rectiligne, de l'articulation 2 jusqu'à l'extrémité distale 21, également pour des raisons de simplicité et de coût de fabrication.The
La distance entre l'extrémité proximale 11 et l'articulation 2 est de préférence comprise entre 5 cm et 20 cm, voire 40 ou 50 cm. La distance entre l'articulation 2 et l'extrémité distale 21 est de préférence comprise entre 5 cm et 20 cm, voire 40 ou 50 cm.The distance between the
De préférence, la partie amont 10 n'est pas constituée d'éléments mobiles. Comme représenté sur les
- un cylindre, s'étendant parallèlement à l'axe amont Δ1, délimité par la
portion rectiligne amont 12, lorsque cette dernière est tubulaire ; - un cylindre s'étendant parallèlement à l'axe amont Δ1, dans lequel la portion rectiligne amont 12 est inscrite. Un tel cas de figure est représenté sur les
figures 5A et 5B .
- a cylinder, extending parallel to the upstream axis Δ 1 , delimited by the upstream
rectilinear portion 12, when the latter is tubular; - a cylinder extending parallel to the upstream axis Δ 1 , in which the upstream
rectilinear portion 12 is inscribed. Such a scenario is shown in thefigures 5A and 5B .
La lumière 15 s'étend, selon l'axe amont Δ1, selon une longueur de préférence comprise entre 2 cm et 20 cm, voire davantage. La lumière 15 permet l'insertion ou le retrait de l'élément de liaison 14. La fonction de l'élément de liaison 14 est de permettre une liaison réversible entre la pièce d'interface 1 et un manche de préhension 30, comme décrit en lien avec la
La portion rectiligne amont 12 comporte deux ouvertures amont 13, diamétralement opposées, ménagées de part et d'autre de l'axe amont Δ1. Le diamètre de chaque ouverture amont 13 est de préférence inférieur à 1 cm. Chaque ouverture amont 13 est dimensionnée de façon à être traversée par un ergot 14' de l'élément de liaison 14, comme représenté sur les
De préférence, la partie aval 20 n'est pas constituée d'éléments mobiles.Preferably, the
Ainsi, de préférence, la pièce d'interface 1 ne comporte que la partie amont 10, et la partie aval 20. Préalablement à l'utilisation, l'élément de liaison 14 est inséré entre les ouvertures amont 13 et/ou entre les ouvertures aval 23 décrites ci-après.Thus, preferably, the
La portion rectiligne aval 22 comporte deux ouvertures aval 23, diamétralement opposées. Ces ouvertures sont destinées à recevoir les ergots 44' d'un élément de liaison 44 d'un outil de nettoyage 40, comme précédemment décrit. Lorsque l'outil de nettoyage 40 est inséré dans la partie aval 20, et plus précisément dans la portion rectiligne aval 22, l'élément de liaison 44 est comprimé, et cela jusqu'à ce que les ergots 44' puissent déboucher à travers les ouvertures aval 23 ainsi qu'à travers les ouvertures de blocage 43 du manche de liaison 42 : cf.

De façon alternative, la gorge peut être ménagée dans la partie amont 10, tandis que la partie aval 20 comporte la surépaisseur annulaire 7.Alternatively, the groove can be made in the
Afin que la conception de la pièce d'interface soit la plus simple possible, il est préférable qu'elle permette une rotation de la partie amont 10 par rapport à la partie aval 20 uniquement autour d'un seul axe de rotation Δ. La pièce d'interface 1 n'autorise pas de mouvement de la partie amont 10 par rapport à la partie aval 20 selon un autre axe de rotation. Ainsi, la pièce d'interface ne permet qu'un seul degré de liberté en rotation. Cela permet de former une pièce d'interface de conception simple, sachant que l'outil 40 peut comporter un degré de liberté en rotation supplémentaire : cf. axe de rotation Δ' décrit en lien avec les
Du fait de la présence du coude 3, sous l'effet de la rotation de la partie amont 10 autour de l'axe amont Δ1, la partie orientable 4 tourne autour du coude 3. La rotation de pièce amont 1 autour de l'axe amont Δ1 est matérialisée par la double flèche F1 sur les
L'orientation de la partie orientable 4 est possible du fait que l'outil de nettoyage 40 soit mobile en rotation autour de l'axe de rotation Δ'. L'axe de rotation Δ' de l'outil de nettoyage 40 est de préférence perpendiculaire à l'axe de rotation Δ défini par l'articulation 2 de la pièce d'interface 1.The orientation of the
Il est usuel que des outils de nettoyage 40, destinés au nettoyage de bassins, soient mobiles en rotation autour d'un axe de rotation Δ' comme décrit en lien avec les

Sous l'effet de l'appui du dispositif de nettoyage 40 contre le plan d'appui, la partie aval 20 est bloquée en rotation autour de l'axe de rotation aval Δ2, du fait de la liaison entre la partie aval 20 et l'outil de nettoyage 40. Lorsque le manche de préhension 30 est actionné en rotation (double flèche F1), la partie orientable 4 tourne, dans un plan parallèle à l'axe de rotation aval Δ2, autour du coude 3. Il en résulte une orientation de l'outil de nettoyage 40, parallèlement au plan d'appui (double flèche F2).Under the effect of the support of the

Comme précédemment décrit, en lien avec le mode de réalisation précédent, la portion rectiligne amont 12 comporte deux ouvertures amont 13, diamétralement opposées, permettant une insertion des ergots 14' d'un élément de liaison 14. La portion rectiligne amont 12 comporte également une lumière 15, permettant de disposer l'élément de liaison 14, de telle sorte que les ergots 14' s'étendent à travers des ouvertures amont 13.As previously described, in connection with the previous embodiment, the upstream
Dans les exemples qui précèdent, on a décrit une pièce d'interface 1 telle que la partie amont 10 est agencée pour s'insérer dans un manche de préhension 30, tandis que la partie aval 20 est agencée pour s'insérer autour d'un manche de préhension 42 d'un outil de nettoyage 40. On comprend que selon d'autres modes de réalisation, la partie amont 10 peut s'insérer autour d'un manche de préhension 30 et/ou la partie aval 20 peut s'insérer dans un outil de nettoyage 40.In the preceding examples, an
Selon un autre mode de réalisation, la portion rectiligne amont 12 de la pièce d'interface 1 s'étend selon une longueur supérieure à 30 cm, voire supérieure à 1m, et typiquement comprise entre 1 m et 4 m. Ainsi, la distance entre l'articulation 2 et l'extrémité proximale 11 est supérieure à 1 m, et est par exemple comprise entre 1 m et 4 m, voire 5 m. La portion rectiligne amont 12 forme alors un manche de préhension 30 de la pièce d'interface, ce dernier étant intégré à la pièce d'interface. Selon ce mode de réalisation, la portion rectiligne amont 12 peut ne pas comporter d'ouvertures amont 13, ni de lumière 15.According to another embodiment, the upstream
L'invention permet, à l'aide d'une pièce simple, ne présentant qu'un seul degré de liberté en rotation, d'orienter, à distance, l'outil de nettoyage, par une simple rotation du manche de préhension 30.The invention makes it possible, with the aid of a simple part, having only one degree of freedom in rotation, to orient, at a distance, the cleaning tool, by a simple rotation of the
