Abstract

Abstract 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.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 176 words
A device for cleaning leaves and other debris from rain-collecting gutters consisting of: (a) rigid handle means; (b) motor means pivotally mounted on one end of the handle means and having a rotatable shaft; (c) switch means mounted on the opposite end of the handle means for actuation of the motor means; (d) means mounted on the motor means shaft for securely clamping a plurality of sections of flexible line on the shaft for rotation with said shaft; (e) each of the sections of flexible line having a preformed configuration having a portion extending in a generally radially outwardly direction and then an integrally connected portion extending in a generally concavely curve direction toward the direction of rotation of the shaft; and (f) roller means mounted on the motor means for engagement with the outer edge of a gutter to facilitate movement of the motor means therealong, whereby the sections of line when rotated by the motor means shaft will scoop leaves and other debris from the gutter due to the preformed configuration of the line.
Claim 2
Independent Claim 176 words
A device for cleaning leaves and other debris from rain-collecting gutters consisting of: (a) rigid handle means; (b) motor means pivotally mounted on one end of the handle means and having a rotatable shaft; (c) switch means mounted on the opposite end of the handle means for actuation of the motor means; (d) means mounted on the motor means shaft for securely clamping a plurality of sections of flexible line on the shaft for rotation with said shaft; (e) each of the sections of flexible line having a preformed configuration having a portion extending in a generally radially outwardly direction and then an integrally connected portion extending in a generally concavely curve direction toward the direction of rotation of the shaft; and (f) roller means mounted on the motor means for engagement with the outer edge of a gutter to facilitate movement of the motor means therealong, whereby the sections of line when rotated by the motor means shaft will scoop leaves and other debris from the gutter due to the preformed configuration of the line.
Claim 3
Dependent Claim 20 words
The cleaning device defined in claim 1 in which the handle means is a plurality of telescopically joined tubular sections.
Claim 4
Dependent Claim 23 words
The cleaning device defined in claim 2 in which the tubular sections are collapsible within each other for compact storage of the device.
Claim 5
Dependent Claim 35 words
The cleaning device defined in claim 1 in which the motor means is an electric motor; in which an electric supply cord extends along the handle means from the motor means to the switch means.
Claim 6
Dependent Claim 62 words
The cleaning device defined in claim 1 in which the roller means includes a pair of rollers adapted to engage a vertical edge of the gutter and a third roller spaced at generally a right angle with respect to said pair of rollers and adapted to engage a horizontal top edge of the gutter for balancing the motor means on the gutter.
Claim 7
Dependent Claim 19 words
The cleaning device defined in claim 1 in which the sections of flexible line are pieces of monofilament nylon.
Claim 8
Dependent Claim 54 words
The cleaning device defined in claim 1 in which the flexible line clamping means is a block of rigid material having a central bore; in which the motor means shaft projects into said bore and is secured therein; and in which clip plate means removably mount the sections of flexible line on the block.
Claim 9
Dependent Claim 93 words
The cleaning device defined in claim 1 in which the motor means has an outer housing; in which the roller means includes bracket means mounted on the motor means housing, said bracket means having a web wall attached to the housing and a pair of spaced end walls; in which the roller means includes a pair of rollers which are rotatably mounted on and extend between the spaced end walls; and in which one of the end walls is formed with a slot with a third roller being rotatably mounted in said slot.
Claim 10
Dependent Claim 14 words
The cleaning device defined in claim 1 in which said motor means is reversible.
Claim 11
Dependent Claim 15 words
The cleaning device defined in claim 1 in which said rigid handle means is expandable.
