发明名称 Rain gutter cleaning device
摘要 A portable, motor-operated cleaning device for removing leaves and other debris from rain gutters on buildings. An electric motor is pivotally mounted on the end of a telescoping rigid tubular handle with the electric cord for the motor extending along the interior of the handle to a switch mounted on the opposite handle end. A plurality of short sections of flexible line are mounted on the motor shaft for rotation with a high velocity by the motor. Each of the sections of line have a preformed configuration having a portion which extends in a generally radially outwardly direction from the shaft and an integrally connected portion which then extends in a generally concavely curved direction toward the direction of shaft rotation. A bracket is mounted on the motor housing and has a pair of rollers which are mounted at right angles with respect to a third roller to provide for rolling engagement with the horizontal and vertical outer edges of a rain gutter. The whirling action of the sections of line in combination with their preformed contour dislodges leaves from the gutter without cutting the same into small pieces. A user of the device walks along the ground below the roof edge and with the extended handle rolls the motor along the gutter on the rollers while energizing the motor by the switch.
