  • Patent number: 6170112
    Abstract: A push broom operable by a person in a more comfortably upright stature and with less force than required in using straight-handled push brooms has a front handle portion which extends conventionally upwardly and rearwardly from a brush block having downwardly depending bristles. The handle includes a posterior portion which angles upwardly and rearwardly from the front handle portion, thereby orienting the rear, upper end of the posterior handle portion is in a more nearly vertical position than that of straight handled brooms. Preferably, the handle is doubly bowed, the posterior portion of the handle including an intermediate handle portion inclined upwardly and rearwardly from the front handle portion, and a rear handle portion inclined upwardly and rearwardly from the intermediate handle portion.
