Abstract
Apparatus for supporting and tilting the collecting chamber of a vacuum cleaner is disclosed including a chassis rollable over a floor surface, having a pair of upstanding arms, a pair of arm members pivotally connected to the upstanding arms of the chassis, and a handle pivotally connected to the arm members. The handle can be locked in either of two positions, with the first push position being such that the gripping portion of the handle is placed above the pivot point of the arm member to the chassis such that the gripping portion is in a position convenient to the operator for rolling the chassis over the floor surface and with the second tilt position being rotated from the first push position about the pivotal connection of the handle with the arm members such that the gripping portion lies below the pivot point to allow pivoting of the arm members on the chassis to tilt the collecting chamber of the vacuum cleaner so that it empties the contents therefrom.
