Patent

CA 2524642

A cleaning appliance, such as a cylinder-type vacuum cleaner (7), comprises a main body (8) having a rear portion (17) and side wheels (12) arranged to allow the main body to travel across a floor surface (11). In normal use, the rear portion is spaced from the floor surface. The rear portion carries a wheel (23) arranged so that, if the main body is tilted so that the rear portion is brought towards the floor, the wheel contacts the floor surface. Thus, the cleaner may be used in a tipped-back position without causing damage to the floor surface as the cleaner is dragged along by the user by means of a hose attached to the main body. The size and position of the wheel is determined so that, when the cleaner is tipped back, the centre of gravity of the main body acts to return the main body to its righted position.

L'invention concerne un appareil à nettoyer, tel qu'un aspirateur à forme ronde (7), qui comprend un corps principal (8) présentant une partie arrière (17) et des roues latérales (12) arrangées de manière à permettre au corps principal de se déplacer sur une surface de plancher (11). Pendant l'utilisation normale, la partie arrière est décalée de la surface de plancher. La partie arrière comporte une roue (23) disposée de sorte que, lorsque le corps principal est basculé entraînant la partie arrière vers le plancher, la roue vienne au contact de la surface de plancher. Ainsi, l'aspirateur peut être utilisé dans une position inclinée vers l'arrière sans endommager la surface de plancher pendant que l'aspirateur est traîné par l'usager au moyen d'un tuyau souple fixé au corps principal. La taille et la position de la roue sont déterminées de sorte que, lorsque l'aspirateur est incliné vers l'arrière, le centre de gravité du corps principal agit de façon à remettre ce dernier dans sa position normale.
