Gutter debris barrier system
A gutter debris barrier system for preventing debris from entering a gutter includes a frame that is attached to a fascia of a building and a filter screen. The frame may include a floor with slots punched therein, with ribs on either side of the slots that form channels. The channels may be tapered to improve the speed and efficiency of heat transfer, and also to funnel water down into the gutter. The frame may be connected to a mounting bracket that is mounted to the fascia. The heating element provides heat throughout the system to prevent ice formation in cold temperatures.
1. A debris barrier system for use with a gutter configured to collect water, the gutter having a bottom, a first inner wall located adjacent to a fascia that extends downwardly from the roof of a building, and a second wall spaced outwardly from the first wall, the debris barrier system comprising:
a frame adapted to overlie at least a portion of the gutter;
wherein the frame has a floor, a first, inner side wall, and a second, outer side wall, all of which extend longitudinally of the gutter;
wherein the frame further comprises at least three longitudinally extending, laterally spaced channels extending along the floor between the inner and outer side walls, the channels being separated from one another by first and second longitudinally extending ribs that extend upwardly from the floor, each of the channels having a plurality of slots formed in the floor;
a filter screen covering at least a portion of the frame, the filter screen capable of allowing water to flow therethrough while precluding debris from passing therethrough; and
an electrical heating element located in contact with the frame, wherein
the slots in each channel are longitudinally offset from the slots in adjacent channels, wherein
the first, inner side wall and the second, outer side wall of the frame are spaced from one another by a transverse distance “D” in a horizontal plane extending therebetween, wherein a thermal transfer path “P” is formed by an uninterrupted serpentine path extending along the surface of the frame from the first, inner side wall of the frame to the second, outer side wall of the frame without crossing any of the slots, and wherein a ratio of P/D is no more than about 5/3.
2. The debris barrier system of claim 1 , wherein each of the channels is generally actuate in shape, and wherein each of the ribs has first and second opposed surfaces, each of which slopes curvilinearly downwardly and outwardly along at least a portion of the height thereof.
3. The debris barrier system of claim 2 , wherein each of the slots extends along a lowest point of the associated channel.
4. The debris barrier system of claim 1 , wherein the filter screen is secured to the inner side wall and outer side wall of the frame using expandable and contractible adhesive.
5. The debris barrier system of claim 1 , further comprising a lip located along the second, outer side wall adjacent to the electrical heating element, wherein the lip is sloped away from the electrical heating element and downwardly towards the bottom of the frame.
6. A debris barrier system for use with a gutter configured to collect water, the gutter having a bottom, a first inner wall located adjacent to a fascia that extends downwardly from the roof of a building, and a second wall spaced outwardly from the first wall, the debris barrier system comprising:
a frame adapted to overlie at least a portion of the gutter;
wherein the frame has a floor, a first, inner side wall, and a second, outer side wall, all of which are configured to extend longitudinally of the gutter;
wherein the frame comprises at least three longitudinally extending, laterally spaced channels extending along the floor between the inner and outer side walls, the channels being separated from one another by first and second longitudinally extending ribs that extend upwardly from the floor, each of the tapered channels having a plurality of slots formed in the floor, at least a substantial portion of an upper surface of each of the channels having a generally concave shape when viewed in transverse cross section;
wherein the frame is attachable to the building and the second wall of the gutter such that the frame is held over the bottom of the gutter;
a filter screen covering at least a portion of the frame, the filter screen capable of allowing water to flow therethrough while precluding debris from passing therethrough; and
an electrical beating element located in contact with the frame, wherein
the slots in each channel are longitudinally offset from the slots in adjacent channels, wherein
the first, inner side wall and the second, outer side wall of the frame are spaced from one another by a transverse distance “D” in a horizontal plane extending therebetween, wherein
a thermal transfer path “P” is formed by an uninterrupted serpentine path extending along the surface of the frame from the first, inner side wall of the frame to the second, outer side wall of the frame without crossing any of the slots, and wherein
a ratio of P/D is no more than about 5/3.
7. The debris barrier system of claim 6 , wherein each of two opposed surfaces of each of the ribs is curved downwardly and outwardly along at least a lower portion thereof such that opposed surfaces and an upper surface of a channel located between the ribs present a generally u-shaped transverse profile.
