Convertible blower and vacuum
First Claim
1. A portable blower-vacuum, comprising:
- a housing having an inlet and an outlet, the outlet disposed along a first axis;
a discharge tube adapted to cooperate with the outlet, the outlet and the discharge tube having complementary engagement faces, the engagement faces nonorthogonally disposed relative to the first axis;
a motor disposed within the housing; and
an impeller adapted to be rotatably driven by the motor to provide an airflow from the inlet to the outlet.

Abstract
A portable blower-vacuum includes a housing having an inlet and an outlet. A motor is disposed within the housing for rotatably driving an impeller to transfer an airflow from the inlet to the outlet. The blower-vacuum also includes an elongated air outlet structure over which an elongated blower tube may be slid for attachment in a blower mode and removed in a vacuum mode. The outlet structure possesses a configuration that improves the ease with which the blower tube may be fitted to the air outlet. The blower-vacuum also includes a cover disposed over the inlet in a blower mode and a skirt adapted to cooperate with the cover and the inlet to substantially reduce or eliminate lateral airflow from entering the inlet from between the cover and the housing.
