Abstract

A nozzle assembly for a vacuum cleaner having a brush (10) of uniform cross section about which the nozzle assembly is constructed around. A plurality of flexible tubes (12) are inserted within brush (10). The bristles of brush (10) extend beyond the ends of tubes (12), communicating with tubes (12) during a cleaning process. A clamp (14) secures tubes (12) within the bristles at evenly spaced locations. Tubes (12) create suction within brush (10) and provide airflow back to the vacuum cleaner. An attachment adapter (16) is formed around the perimeter of clamp (14) and enables the nozzle assembly to be connected to the vacuum cleaner.

Claims

1. A nozzle assembly for attachment to a vacuum source, said vacuum source which creates a suction flow of air through vacuum openings, said nozzle assembly providing for the scouring and removal of dirt from tight, hard-to-reach places, said nozzle assembly comprising:

(a) a spaced array of open-ended tubes, said tubes parallel to one another axially, said tubes in flow communication with said vacuum source so as to provide suction;

(b) a brush element formed by a plurality of bristle members, said bristle members filling the space between said tubes;

(c) means for holding said bristles and tubes in a fixed relationship; and

(d) means for flow connecting said nozzle assembly to said vacuum source.

2. The nozzle assembly of claim 1, wherein said tubes are of shorter length than said bristles.

3. The nozzle assembly of claim 1, wherein said tubes are comprised of flexible material.

4. The nozzle assembly of claim 1, wherein said tubes are of annular cross section.

5. The nozzle assembly of claim 1, wherein said brush is of a cylindrical shape.
