Abstract

The specification discloses a sweeper in which a combined tubular frame and handle member comprising a generally U-shaped forward frame portion which is continuous with an upwardly and rearwardly extending handle portion serves as the focal point of the sweeper design. The combined tubular frame and handle member is mounted on a brush housing, serves to facilitate support of a dust bin, and serves as the focal point for additional design features such as a body cradling upper handle portion, a hand hold at the front of the dust bin and a pivotal side brush mount.
