CA 2345601
A self-propelled upright vacuum cleaner is provided having a lower portion and an upright handle portion pivotally attached to the floor engaging portion for a pivotal motion between an upright storage position and a pivotal operating position including a transmission operatively connected to a drive wheel and a motor drivingly connected to the transmission for driving the drive wheel in forward and reverse. A clutch engaging member is pivotally mounted to the floor engaging portion adjacent to the transmission for pivotal motion about a pivot axis located generally at a forward portion of the clutch engaging member. Operably associated with the clutch engaging member is a transverse linking member that reciprocates from a neutral position in first and second directions in response to pivotal motion of a bottom link. The reciprocation of the transverse link selectively moves said clutch engaging member from a neutral position to a forward drive position and a reverse drive position. A finger link member carried on the housing assembly is selectively positioned in a channel formed on the bottom link, relative to the pivotal positioning of the housing assembly. Pivotal motion of the finger link engages the bottom link member when the housing assembly and handle portion are in an operative inclined position and does not engage the bottom link member when the housing assembly and handle portion are in a storage upright position.
