Abstract
Abstract The tool of the present invention is comprised of a scoop having flexible side walls which, at the mouth of the scoop, normally are wider and higher than the gutter into which the tool is to be inserted. The side walls become progressively narrower extending away from the mouth of the scoop and terminate in a heel at the closed end of the scoop which is considerably narrower than its mouth. In addition, the heel is relatively inflexible thereby allowing it to be inserted into a gutter which is much smaller than the remainder of the scoop. Once the heel is in place the remainder of the scoop can be inserted into the gutter by rotating the scoop downwardly while drawing the tool backwardly along the length of the gutter. Once in place the flexible side walls will conform to the shape of the gutter thereby completely filling the gutter. After the tool is inserted the gutter is cleaned by sliding the tool along the gutter until it is full. A handle located above and behind the heel of the scoop assists the user in inserting the tool and in moving it to clean the gutter. A low-walled tongue located at the front of the scoop, in front of the mouth, facilitates removing debris from beneath the spikes which attach the gutter to the roof.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
A tool for removing debris from a rain gutter having a generally U-shaped cavity, said tool comprising: (a) a U-shaped scoop having open and closed ends and an integral bottom and side walls, said side walls being easily deflected sufficiently to permit a scoop having a larger transverse dimension than a particular gutter cavity to be inserted into the gutter cavity and conform to the shape of the gutter cavity when inserted therein; (b) a heel located at the closed end of said scoop which is narrower than the remainder of said scoop and which is relatively inflexible; and (c) handle means for inserting said heel into a gutter and for thereafter rotating the tool to conformingly insert said scoop into said gutter.
Claim 2
Dependent Claim
123 words
A tool for removing debris from a rain gutter having a generally U-shaped cavity, said tool comprising: (a) a U-shaped scoop having open and closed ends and an integral bottom and side walls, said side walls being easily deflected sufficiently to permit a scoop having a larger transverse dimension than a particular gutter cavity to be inserted into the gutter cavity and conform to the shape of the gutter cavity when inserted therein; (b) a heel located at the closed end of said scoop which is narrower than the remainder of said scoop and which is relatively inflexible; and (c) handle means for inserting said heel into a gutter and for thereafter rotating the tool to conformingly insert said scoop into said gutter.
Claim 3
Dependent Claim
36 words
The tool of claim 1 wherein the side walls are shorter proximate the open end of said scoop than they are over the remainder thereof to provide a low-walled tongue at the front of said scoop.
Claim 4
Dependent Claim
27 words
The tool of claim 2 wherein the separation of said side walls is the greatest immediately inwardly of said tongue and progressively decreases moving toward said heel.
Claim 5
Dependent Claim
56 words
The tool of claim 3 wherein the thickness of said side walls progressively decreases, proceeding from the handle means to the tongue thereof, and the scoop is sufficiently flexible that said scoop will widen out in shape as pressure is applied through said handle means with the tool positioned inside said gutter, thereby filling said gutter.
Claim 6
Dependent Claim
12 words
The tool of claim 1 wherein said scoop has a U-shaped cross-section.
Claim 7
Dependent Claim
37 words
The tool of claim 1 wherein said handle means comprises an elongate handle which is attached to said heel above the top of said side walls and which extends therefrom in the opposite direction of said scoop.
Claim 8
Dependent Claim
184 words
A tool for cleaning gutters comprising: (a) a scoop having flexible side walls which can easily be deflected to conform to the shape of the gutter when said scoop is inserted therein, said side walls being shorter proximate the open end of said scoop than they are over the remainder thereof to provide a low-walled tongue at the front of said scoop; (b) a heel located at the closed end of said scoop which is narrower than the remainder of said scoop and which is relatively inflexible; (c) wherein the separation of said side walls is greatest immediately inwardly of said tongue and progressively decreases moving towards said heel; (d) handle means for inserting said heel into a gutter and for thereafter rotating the tool to conformingly insert said scoop into said gutter; and (e) wherein the thickness of said side walls progressively decreases, proceeding from said heel to the said tongue, and said scoop is sufficiently flexible that it will widen out in shape as pressure is applied through said handle means with the tool positioned inside said gutter, thereby filling said gutter.
Claim 9
Dependent Claim
184 words
