Abstract

A blower attachment (15) comprising a frame (16) having a connecting assembly (18) for releasably connecting to a blower (35), a housing (19) supported by the frame and enclosing a chamber (20), the housing having a top portion (21), a bottom portion (22) and side portions (23a-d), an inlet (24) to the chamber in the top portion of the housing, the inlet having a maximum inlet width (34), a conduit (25) adapted to extend between the inlet and a blower outlet port (36), multiple baffles (26a-h) in the chamber orientated vertically and extending from a first point (27a-d) below the inlet to a second point (28a-d) peripheral to the inlet, an outlet (29) from the chamber positioned below the inlet and having a maximum outlet width (73) greater than the maximum inlet width, an adjustment mechanism (30) adapted to adjust the height of the outlet relative to an underlying surface (38), the conduit, inlet, chamber, baffles and outlet adapted to direct flow (79) from the blower through the inlet into the chamber and out the outlet against the underlying surface.

Claims

1. A blower attachment comprising:

a frame having a connecting assembly for releasably connecting to a blower;

a housing supported by said frame and enclosing a chamber;

said housing having a top portion, a bottom portion and side portions;

an inlet to said chamber in said top portion of said housing;

said inlet having a maximum inlet width;

a conduit adapted to extend between said inlet and a blower outlet port;

multiple baffles in said chamber oriented substantially vertically and extending from a first point below said inlet to a second point peripheral to said inlet;

an outlet from said chamber having a maximum outlet width greater than the maximum inlet width;

said conduit, inlet, chamber, baffles and outlet adapted to direct airflow from an attached blower through said inlet into said chamber and out said outlet against an underlying surface.

2. The blower attachment set forth in claim 1, and further comprising an adjustment mechanism adapted to adjust the height of said outlet relative to said underlying surface.

3. The blower attachment set forth in claim 1, and further comprising a containment skirt extending below and around at least a portion of the peripheral edge of said outlet.

4. The blower attachment set forth in claim 3, wherein said containment skirt comprises flexible fibers adapted to brush said underlying surface.
