Patent

CA 2457712

A vaccum cleaner has a hose (10, 30, 30') that is retractable in length by the application of reduced pressure from the vacuum cleaner. After use, the free end (14, 21, 33) of the hose is occluded so that pressure falls within the hose and it is retracted in length. The hose is restrained in its shortened length before suction is turned off. The hose in its retracted state may be stored on or off the vacuum cleaner.

L'invention concerne un aspirateur constitué d'un tuyau (10, 30, 30') pouvant être rétracté dans la longueur par application d'une faible pression à partir de l'aspirateur. Après son utilisation, l'extrémité libre (14, 21, 33) du tuyau est occluse de manière que la pression baisse à l'intérieur du tuyau et que ce dernier puisse être rétracté dans la longueur. Le tuyau est immobilisé dans sa longueur et raccourci avant la mise hors tension de l'aspirateur. Le tuyau dans son état rétracté peut être stocké sur l'aspirateur ou indépendamment de celui-ci.
