ABSTRACT:
A portable hand-held convertible blower and vacuum unit having a primary handle on the housing and a secondary handle located on the vacuum tube attachment. The secondary handle comprises a generally compliant gripping surface and enables the operator to connect or disconnect the vacuum tube from the housing in order to convert the unit from blower to vacuum mode or vice versa. The connection between the vacuum tube and the unit housing comprises a bayonet fitting. The handle also affords a second gripping surface for use of the unit during vacuum operation. Since the handle is attached to the vacuum tube, the handle does not hinder use of the unit during blower operation during which the vacuum tube is removed from the housing. When the vacuum tube is attached to the unit housing, the longitudinal axis of the gripping surface of the secondary handle is approximately perpendicular to the longitudinal axis of the primary handle that is connected to the housing.
