Abstract

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, providing a planar stiffness to the mesh causing the mesh to be self-supporting over a gutter; 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, wherein the gutter debris preclusion device, when attached directly or indirectly to a gutter does not require a separate support mechanism to keep the mesh substantially planar over the gutter.

First claim

What is claimed is:

1. A gutter debris preclusion device for securing to a top portion of a roof gutter that is attached to a 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 sized to substantially cover a rain gutter;
corrugations formed in the mesh, providing a planar stiffness to the mesh causing the mesh to be self-supporting over a gutter; and
a debris collection trough disposed along a longitudinal axis of the mesh, having a bottom angled portion with first and second wall portions connected to the bottom angled portion, the first wall portion extending from the bottom angled portion towards a rear gutter end of the mesh and longer than the second wall portion, when attached to the roof gutter, the second wall portion extending from the bottom angled portion towards a front gutter end of the mesh, wherein the bottom angled portion is adjacent to and positioned below a gutter lip, wherein, when attached to the roof gutter, the trough provides a horizontally angled, substantially L-shaped reservoir below the gutter lip,
wherein the gutter debris preclusion device, when attached to a gutter does not require a separate support mechanism and wherein the corrugations extend within the trough.

2. The device of claim 1 , wherein the mesh is formed from stainless steel wires, plastic, expanded metal, perforated metal, slotted metal or louvered metal.

3. The gutter debris preclusion device as recited in claim 1 , wherein the bottom angled portion has a distinct edge.

4. The device of claim 1 , wherein the corrugations in the mesh are formed via at least one of stamping, pressing, and weaving.

5. The device of claim 1 , further comprising:
a front strip connector adapted to connect the front gutter end of the mesh to a front of the gutter; and
a rear strip connector adapted to connect the rear gutter end of the mesh to either a rear of the gutter or a roof element neighboring the gutter.

6. The device of claim 5 , wherein the trough is displaced up to 1.5″ from the front strip connector.

7. The device of claim 5 , wherein the trough is displaced up to 0.25″ from the front strip connector.

8. The gutter debris preclusion device as recited in claim 1 , wherein the bottom angled portion is at an angle that is greater than 90 degrees.

9. The gutter debris preclusion device as recited in claim 1 , wherein the first wall portion is longer than a majority of the lateral width of the mesh.

10. The gutter debris preclusion device of claim 9 , further comprising a second inverted V-shaped-trough adjacent to the first inverted V-shaped trough.

11. The device of claim 1 , wherein the corrugations span from the rear gutter end of the mesh to a first bend in the trough.

12. The device of claim 1 , wherein the corrugations span from the rear gutter end of the mesh to a second bend in the trough.

13. A gutter debris preclusion device for securing to a top portion of a roof gutter that is attached to a 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 sized to substantially cover a rain gutter;
corrugations formed in the mesh, providing a planar stiffness to the mesh causing the mesh to be self-supporting over a gutter; and
at least one first debris collection, inverted V-shaped-trough disposed along a longitudinal axis of the mesh and, when attached to the roof gutter, proximal to a gutter lip, wherein a peak of the trough(s) is higher than the gutter lip,
wherein the gutter debris preclusion device, when attached to a gutter does not require a separate support mechanism and wherein the corrugations extend within the trough.

14. A gutter debris preclusion device for securing to a top portion of a roof gutter that is attached to a 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 sized to substantially cover a rain gutter;
corrugations formed in the mesh, providing a planar stiffness to the mesh causing the mesh to be self-supporting over a gutter; and
a plurality of first debris collection, V-shaped-troughs adjacent to each other and disposed along a longitudinal axis of the mesh and, when attached to the roof gutter, proximal to a gutter lip,
wherein the gutter debris preclusion device, when attached to a gutter does not require a separate support mechanism and wherein the corrugations extend within the trough.

15. A gutter debris preclusion device for a roof gutter having a gutter lip for keeping leaves and other debris out of the roof gutter while allowing water to pass thereinto, comprising:
a sheet of mesh; the sheet of mesh having an upper edge adapted to be located above a lower edge and with the sheet of mesh overlying the roof gutter; the sheet of mesh including a plurality of corrugations extending at least part of the way from said upper edge to said lower edge;
a trough having a bottom angled portion and a wall portion connected to the bottom angled portion, the trough disposed in the sheet of mesh along a longitudinal axis of the sheet of mesh and spanning a majority of a lateral width of the sheet of mesh, wherein, when attached to the roof gutter, the bottom angled portion of the trough is below and proximal to a top of the gutter lip and the wall portion rises from the bottom angled portion to above the gutter lip; and,
wherein said lower edge being adjacent the gutter lip when the system is in use, wherein the trough with the bottom angled portion and wall portion provides an angled L-shaped reservoir so that water is allowed to pass through the sheet of mesh into the roof gutter, and wherein at least one of the corrugations extends from at least one of the upper edge and the lower edge.

16. The gutter debris preclusion device as recited in claim 15 , wherein at least one of the plurality of corrugations extends through the first trough.

17. The gutter debris preclusion device as recited in claim 15 , wherein at least one of the plurality of corrugations extends partially through the first trough.

18. The gutter debris preclusion device as recited in claim 15 , wherein the first trough is disposed in the sheet of mesh to be disposed within the gutter when the device is in use.

19. The gutter debris preclusion device as recited in claim 15 , further comprising a second trough disposed in the sheet of mesh along a longitudinal axis of the sheet of mesh.
