Dans la présente description, par aspirateur ou ensemble d'aspiration de type traineau, il est fait référence à un aspirateur ou ensemble d'aspiration pouvant se déplacer en roulant sur le sol par exemple à l'aide de roues ou roulettes lorsque l'aspirateur est en situation d'usage. Dans un aspirateur traineau, un suceur d'aspiration est connecté à l'ensemble d'aspiration via un tube d'aspiration comprenant une partie rigide et une partie flexible. Lors d'une opération de nettoyage, l'utilisateur d'un aspirateur traineau tient le suceur d'aspiration via une poignée ménagée sur la partie rigide du tube d'aspiration ou solidaire du tube d'aspiration. Un aspirateur traineau est généralement tiré par l'utilisateur via la poignée et la partie flexible du tube d'aspiration, ce mode de déplacement est à l'origine de l'appellation « aspirateur traineau ». L'appellation aspirateur traineau ou ensemble d'aspiration traineau couvre aussi des aspirateurs à roues ou roulettes motorisés et capables de suivre les déplacements du suceur d'aspiration, de la poignée ou de l'utilisateur.In the present description, by vacuum cleaner or sled type suction assembly, reference is made to a vacuum cleaner or suction assembly which can move while rolling on the ground for example using wheels or casters when the vacuum cleaner is in use. In a canister vacuum cleaner, a suction nozzle is connected to the suction assembly via a suction tube comprising a rigid part and a flexible part. During a cleaning operation, the user of a canister vacuum cleaner holds the suction nozzle via a handle provided on the rigid part of the suction tube or secured to the suction tube. A canister vacuum cleaner is generally pulled by the user via the handle and the flexible part of the suction tube; this mode of movement is the origin of the name “candle vacuum cleaner”.

La roue additionnelle 38 est configurée pour rouler sur le sol lorsque la trappe d'accès 26 occupe la position de fermeture et lorsque l'ensemble d'aspiration 1 reposant sur le sol à nettoyer est par exemple tiré par l'utilisateur. De façon avantageuse, lorsque l'ensemble d'aspiration 1 est déplacé vers l'avant, l'axe de rotation A38 de la roue additionnelle 38 est sensiblement parallèle à l'axe de pivotement de trappe A26.The additional wheel 38 is configured to roll on the ground when the access hatch 26 is in the closed position and when the suction assembly 1 resting on the floor to be cleaned is for example pulled by the user. Advantageously, when the suction assembly 1 is moved forward, the axis of rotation A38 of the additional wheel 38 is substantially parallel to the hatch pivot axis A26.

Selon le mode de réalisation représenté sur les figures, lorsque les première et deuxième roues principales 17, 18 et la roue additionnelle reposent sur une surface horizontale, l'axe de rotation A38 de la roue additionnelle 38 est plus proche de la surface horizontale que l'axe de pivotement de trappe A26. De façon avantageuse, l'axe de rotation A38 de la roue additionnelle 38 est situé entre les axes de rotation des première et deuxième roues principales et l'axe de pivotement de trappe A26.According to the embodiment shown in the figures, when the first and second main wheels 17, 18 and the additional wheel rest on a horizontal surface, the axis of rotation A38 of the additional wheel 38 is closer to the horizontal surface than the hatch pivot axis A26. Advantageously, the axis of rotation A38 of the additional wheel 38 is located between the axes of rotation of the first and second main wheels and the hatch pivot axis A26.

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