Abstract
Apparatus for reducing tipping forces applied to an upright cannister-type vacuum cleaner when pulled by an elongate flexible intake hose connected thereto including an elongate strap, means for releasably connecting one end of the strap to a point on the appliance body to beneath the intake hose connector and means for adjustably attaching the other end of the strap to a portion of the hose spaced from the hose connector. When pulling forces from the user are applied to the vacuum cleaner body through the intake hose while vacuuming is being performed, the strap redirects at least a portion of the pulling forces away from the hose connecting means and to the vacuum cleaner body at the strap connection point. The redirection of the pulling forces both increases the upward directed component thereof to decrease friction opposing rolling motion of the vacuum cleaner body, and reduces the effective moment arm and thus the force moment of the horizontal component of the pulling force tending to tip the apparatus about its base.
