Self-supporting bi-directional corrugated mesh leaf preclusion device
A roof gutter for the purpose of keeping small debris out of the gutter and allowing rainwater to pass into the gutter. The covering is comprised of a water permeable, weather resistant mesh having apertures of a pre-determined size for passing water, the mesh sized to substantially cover a rain gutter; corrugations formed in the mesh; a debris collection first trough disposed along a longitudinal axis of the mesh, formed by making at least two bends in the mesh, the first trough located between a longitudinal midline of the mesh and a front gutter end of the mesh.
1. A gutter debris preclusion device for securing to a top portion of a prospective roof gutter that is attached to a prospective building for keeping leaves and other debris out of the roof gutter, comprising:
a water permeable, weather resistant mesh having apertures of a pre-determined size for passing water, the mesh having a roof side, a gutter lip side proximal to a prospective gutter's gutter lip, and a gutter lip portion terminating the gutter lip side, wherein the mesh is sized to substantially cover the prospective rain gutter attached to the prospective roof;
corrugations in the mesh; and
a trough disposed along a longitudinal axis of the mesh and positioned proximal to the gutter lip portion, the trough comprising:
a longer first wall having a first end extending towards the roof side of the mesh and a second end extending towards the gutter lip side of the mesh; and
a shorter second wall joining the second end of the longer first wall, the shorter first wall rising upwards towards the gutter lip side of the mesh and connecting to the gutter lip portion, wherein a shape of the first and second wall form a 2-sided reservoir, and a most bottom point of the reservoir is lower than the gutter lip portion.
2. The device of claim 1 , wherein an angle of the joined longer first wall and shorter second wall is greater than 90 degrees.
3. The device of claim 1 , the mesh is formed from stainless steel wires, plastic, expanded metal, perforated metal, slotted metal or louvered metal.
4. The device of claim 1 , wherein the corrugations are configured to provide a planar stiffness to the mesh causing the mesh to be self-supporting over the gutter.
5. The device of claim 1 , wherein the corrugations in the mesh are formed via at least one of stamping, pressing, and weaving.
6. The device of claim 4 , wherein the corrugations are within the trough.
7. The device of claim 1 , further comprising:
a front strip connector adapted to connect the gutter lip portion to a front of the gutter; and
a rear strip connector adapted to connect a roof side end of the mesh to either a rear of the gutter or a roof element neighboring the prospective gutter.
8. The device of claim 7 , wherein the trough is displaced up to 1.5″ from the front strip connector when the device is connected to the front/rear connector.
9. The device of claim 7 , wherein the trough is displaced up to 0.25″ from the front strip connector when the device is connected to the front/rear connector.
10. The device of claim 1 , wherein the corrugations span from the roof-side of the mesh into the first wall.
11. The device of claim 1 , wherein an angle of the joined longer first wall and shorter second wall is less than 90 degrees.
12. The device of claim 1 , wherein at least one of the first and second walls contains another angled bend to form a segmented or a curved reservoir bottom.
